I love my speed booster. You can also remove the EFS adapter from some of the EFS lenses, and they will work with the speed booster also. I actually cut the plastic EFS mount off of my EFS 10-18mm lens so I could use it with the speed booster on my Canon M6-II and it works GREAT for video when I need a wide angle.
Mark, describing the difference in such a way that it is easier for a beginner to understand, i appreciate. I own the Adapter but now i will get the speed booster because now i understand the options it will provide me. Thank you for what you are doing, and the link.
I’m watching your videos and despite English isn’t my main language, your explanations are so clear, that i sometimes understand the theme better with your videos than with videos on my native language. Great work!
The easy answer is get both. You need both. And while you are on it also buy a tele-converter. (However it might be a bit complicated to get a Metabones EF-M / EF speedbooster ... since they ship from HongKong) and no shop has them on the shelf. Some has the viltrox... but that´s comes with visibly inferior image quality in regards of sharpness.
Good summary, I started with the adapter and have since bought the speed booster. I tend to have my nifty50 on the speed booster for the wider angle and bokeh effect, then the adapter on my zoom lens. Great combo I reckon, although my speed booster seems to be missing it's software... Still works and I normally manually focus anyhow. Im on the old m3 but still takes fantastic shots.
I love my M50ii! But after watching countless videos of creators jumping ship to Sony, part of me wonders whether or not it’s worthwhile sticking around to see what’s up with the EF or EF-M series… would love your point-of-view in any upcoming videos!

@@markwiemels I love my m6 mark ii, but I'm really missing a fast super wide angle auto focus lens for it. There's the Samyang 12mm f2, but the auto focus version for ef-m doesn't exist.
@@markwiemels It’s doing a great job for what I need but any time I think of upgrading beyond the kit lens, there are so many opinions about “don’t invest in EF or EF-M lenses coz Canon hasn’t” so then I’m stuck wondering what to do.

I flipped back and forth on my opinion. I had the booster and then sold it. Then bought it again because I missed the versatility of it. Then sold my M50 with the booster. My final opinion was I liked having it. I would not hesitate to recommend it to anyone that's looking for versatility with the lenses that they have. It's another tool to add to your kit.
I have both. Just got the speed booster yesterday. I tested last night the lower f stop, with interesting results. Canon 80 1.8 now a 1.2. 50 1.4, still a 1.4. 17-40 4.0l, now 2.8. Same for 24-105. I will update the firmware tonight and see if it changes.
Nope. The f-stop doesnt change the aperture so speedbooser doesnt affect the dof by itself. It does that because it changes fov and the distance from the subject changes. Dof is not shallower compared to ff but you get more light.
I just received 2 adapters…ordered via Amazon yesterday….EF-M for FD and EF-M for EF/EF-S lenses. Still learning my M50 Mark II, though (bought it over a year ago). I got a Canon A-1 with 4 lenses and Rebel EOS T2 with one lens in a lot of cameras I won in a silent auction a couple of years ago. Decided to try out the 5 lenses.
Great summary (as usual)! I have both for very specific reasons. I have the straight adapter for use on my EF-S 55-250 which gives longer reach than the native M lens in that category at a lower price point, and also for my Sigma 17-50mm fixed f/2.8 zoom which is a lovely (albeit bulkier) replacement for the kit lens and great in low light. But I have the Speed Booster for use with my vintage Helios M44-2 EF mount adapted lens for exactly the reasons you described - namely, the intended wider field of view and the artistic effect of the classic “swirly Bokeh” with that lens.
I have both Viltrox adapter and speedbooster. I got a M6 mark II. Now that everyone is buying the RF lenses, I am still using EF, EF-S and EF-M lenses that I already have.
I have both. I love the fact that it’s almost like having 2 focal lengths in one lens. I want an almost actual 50mm? Speed booster. I want 85mm? Adapter. Also I’ll definitely buy a couple more ef lenses to really utilise this method and since I’m still a beginner it’s a good hands on and cheap way to figure out what focal lengths are good for certain situations so whenever I upgrade to full frame I know what good lenses I’d wanna fork the money out for!
Hi, Mark! Thank you so much for every single one of your videos, really great. I just get the M50 mark ii and a good guide like this is really helpful, I hope you keep making content for the M50, at least for the M mount, beginners like me need comprensibles messages like yours. Hope you doing fine, gracias.
Thank you for this explanation ❤ I used a 50mm lens with the adapter on my Canon M50 Mark II last night for some astrophotography and was so confused as to why the image appeared so zoomed in / cropped. I think I understand why now after watching your video. So thank you!
Hi Mark, I had to revisit this video, after some time, as I was unsure of which way to go the first time around. Having taken the time to review the options, and rethink about what I was looking for, it's the adapter I want, not the speed booster. I am not looking to change my M50 ii anytime soon but wanted to consider the EF & EF-S lenses for their quality. Too bad Canon abandioned us M series owners. Lesson learned Canon. I'll be buying used. Thanks for your info and clear presentation.
thank you - i have a Blackmagic with 25mm lens but the crop factor is too much...i would like a Wider field of view ...hope the booster will help me - nice video thanks for making it...
I watched your last video, thank you so much for giving us your opinion and all of this information, this will be my first time using a "professional" camera after wanting one ever since graduating High School and your videos are in very helpful for me to understand the photography world. I wish you the best!
Thank you so much for this clear, concise explanation! Just ordered a speedbooster along with a 50MM lens for my M50. Very excited to try it out after watching this!
@@markwiemels Have you noticed that the auto focus is significantly slow with this set up? I love the quality while its in focus...but auto seems pretty unreliable as of right now. Im wondering if its something on my M-50s end, or if its the speed booster/50 MM on their own.
Most of my lenses are EFS or M lenses. My only EF lens is the 50mm 1.8. No need for the speed booster for the 50mm lens, since I have a Sigma 30mm 1.4. So…I just use the Viltrox non-speed booster adaptor.
I personally only use the speed booster with the canon 50mm 1.8, and that’s it. I think it’s great honestly and I can’t tell a difference in image quality. I do have both adapters though, both from Viltrox. I use the regular adapter with my Sigma 18-35mm!
I want to buy my first camera for photography and I decided to buy the m50 mark ii, how’s it going so far from you? I’ve realized the kit lens isn’t too great so I’m going to buy the 50 mm f/1.8 lens.
Thanks for this review. I don't mind if it gives my pictures a more vintage look.. I have a Yongnuo 35mm F2 lens I use on my 90D and R7 and its sharp, but nothing compared to a Canon 35mm. But I love the look and its one of my absolute favorite prime lenses. Just give my images a unique vibe
I was just thinking about this I don't have any EF or EFS lenses but I may eventually move to a full frame camera and would invest in those lenses. I plan on sticking with Canon. I have a friend that is a professional and has lots of Canon lenses I could borrow so I may get both starting with the regular.
I'm a pro potographer and looking at buying either an M50 or the mark II for street photography, I do quite a lot of night time street photography. I've been looking at the spec's and cant really see a lot of difference, I already use full frame canon cameras. Could you tell me is there any major difference between the two, please?
I have a m50 mark 2 and with the speedbooster and a low light lens what higher priced cameras would it be equivalent to when decked out? Also a few years down the road I want to upgrade to a 4k/30fps full frame low light camera what would be the best priced camera? Im gonna get used so the cameras around now will be what im getting in a few years to save money.
Why would I do buy a speed booster? Because of the crop factor. Easy to answer. IF I want to use a 11 to lets say 24 mm prime lens, I have no other option. Sadly. Especially not with a good f-stop and auto focus. I wish there would be lenses that have ultra wide angles to counter the crop factor. But there aren't.
First, let me say thank you for this video because I watched some of your other videos and you mentioned a speed booster and I am new to cameras so I was like what is that and then I see this video so thank you so much for making these videos.
I have a canon t7i and a kit lens and a canon 50mm 1.8 lens which one is better to film beauty makeup videos and would I need an adapter or a speed booster?
Hi Mark - so would the booster essentially turn a EF-M 11-22mm into a (rounded up) 8-16mm lens, with the bonus of having it a few f-stops lower increasing the overall aperture? I like the idea of just having to buy the booster without buying such an expensive lens for the same result, as a wide aperture, zoomable lens with a decent range is very pricey. So I wouldn't mind a small degrade in quality if it meant I can achieve a slightly wider FOV as well as having a few f-stops lower.
The speed booster adapts EF lenses to work on EF-M cameras, so doesn’t work on EF-M 11-22mm, but other than that yes, wider field of view and larger aperture (more light).
Hello 👋 ! So I have a m50 ii , I was thinking to buy a tamron 24-70 f2.8 g2 , the question its what you recommend : speed booster or adapter ? Thank you 🙏
Great video, but do you recommend me to buy the speedbooster and then buy 50 mm canon lens or do you recommend me to buy a Sigma 30 mm or viltrox 23 mm 1,4?
The image quality out of the 23mm and 30mm will be better. Have a look at my best prime lens video, it will help you choose the focal lengh. Be sure the watch the start of the video.
@@markwiemels can you please tell me the title of the video I should check from your channel? Thank you in advance UPDATE: I already found it and I am watching it.
My guess is, that if you achieve the same reproduction size on the sensor, the bokeh wont be different, but the sharpness would be better without the speed booster.
I think the physics are that with the speed booster you can get closer to the subject, because of the wider field of view, and this is what gives you more blur… I think..
I'm still confused. So I am an aspiring real estate photographer. I have a Canon M50 Mark ll. I bought a EF-M 11-22mm F4.0-5.6 IS STM Lens. Because of the crop factor of 1.6 my 11mm becomes 17.6mm. IF I get a speed booster will I have a larger field of view more accurate to 11mm or 12mm?
We need both because the speed booster does not support ef-s. I use the speed booster for the nifty fifty. It makes it act like f 1 .2 instead of f 1.8
I beleive you are wrong about speed boosters always reducing resolution. The speed booster does need to consider the lens design. A well corrected lens is going to send the light to the sensors in cones with points st the sensor. The speed booster only needs to increase that angle and it is the same range over then entire frame, regardless of the lens focal length or aperture. If the original lens has aberrations the speed booster may make it worse but I have used speed boosters on my Nikkor 180mm f/2.8 AI and it still out resolves my APS sensor. My experiencxe is that these work very well on very good, sharp lenses at full aperture..
Hello, excellent video! Question: I have an excellent Nikkor 50mm 1.2 lens I want to use on my M50. I got an adapter for Nikkor to EF-M but the crop factor is to big. What would be an effective way to fit than lens to my camera in all "full frame glory", so to speak? Thanks!
Brilliant and informative video yet again Mark. Really want to get the "Sigma 100-400mm f/5-6.3 DG OS HSM contemporary lens for my M50 mk ii (with the ef-m mount adapter of course) for wildlife and surf photography. The performance on an APS-C with an adapter should maintain similar image quality right? Thanks mate
Yes, I believe that would be a good setup, and sports and wildlife specialist oft keep a full frame body, and APS-C body, specifically to use that crop sensor reach. So that lens probably gets used like this all the time.
I have a M50 mark II. I recently purchased a speed booster. However, when I use it with a Tokina 11-16mm lens I get vignetting on 11-13mm focal lengths. Is this normal or a defect? Do I need to change a setting to remove the vignetting?
That’s an APS-C lens, the speed booster takes a full frame image and squeezes it onto the smaller sensor. So essentially that lens and the speed booster are not meant to go together, so yes, what you are seeing is normal.
so if i were to buy sigma 18-35/1.8 DC HSM CANON and mount it to canon m50 mark II... then should i get a speed booster? that's gonna be my first youtube setup so sorry if u are get tired of those questions.. - would really really appreciate ur recommendation! (just need a wide lense cuz sigma 16 f.14 turnt out to be to narrow for the small room i am shooting at)
Question for you. I have a M50 and a collection of 5 EF-M glass. I'm just a photographer with no EF lens. Do you think its worth it to start investing in a speed booster, Adapter and EF glass or in the long run just better to go with a RF second camera like RP and/or R7? PS I do want a second camera. The question is over the value of delaying getting a second camera.
The EF lenses do allow you to use them with RF cameras, and they are more affordable than RF lenses. RP is a lot of camera for the money, I’m a big fan.
Buy lenses for a need not as an investment. If you need a new lens you might consider adapting EF lenses for future compatibility. Of you go to EOS R later then you likely want to buy RF lenses so the EF lenses would be a compromise.
Will the Viltrox Speed Booster work for the Canon M50 with a Laowa 9mm f/2.8 manual focus lens for Canon ef-m mount? I'm trying to get more light in and wider 4k shooting real estate. Thx!
What is the question in the video even supposed to mean? If you wanna buy full frame glass, then you use the speecbooster. If you wanna use APSC glass then use the adapter. That's what they're designed for. Am i missing something?
Yes, you can use FF glass with or without the speed booster. The speed booster gives you a wider field of view and more light, at the sacrifice of image quality and detail. So that is the choice, and trade-off, that is being made.
@@markwiemels Right, but if you'd plan on using a FF lens with the adapter instead of a speedbooster then you might as well get the apsc equivalent of that lens instead. It's gonna be cheaper and smaller. So getting FF lenses to then just put them onto an adapter seems counter intuitive to me.
@@toastbrot97 That's not an unreasonable way to think about it, but it's not quite as simple as that. i.e. the very popular EF 50mm f1.8 does not really have a comparable APS-C lens at the a same price point. So it's not quite a 1:1 thing. None of the FF options will have an exact APS-C match, even though some may be close enough. Plus the speed booster on f1.8 FF gets you a f1.2 equivalent on APS-C, but with some sacrifices.
A lot of lenses are sharper in the center than in the periphery. An adapter will crop off the periphery effectively giving you a sharper image than on a full frame camera. An ideal adapter which introduces no distortion will preserve the peripheral distortion of the full frame lens. Real life lenses will of course introduce transmission effects.
Great video and it explains a lot! But I do have one question and I would be happy if you could help me. I plan to buy 18-400mm F/3.5-6.3 Di II VC HLD which is EF lens but designed for crop sensor. Will speedbooster work with this lens or should I use the adapter? Thank you!
Bought the Viltrox Speed Booster M2 off your affiliate link ;). Question though: Using it with a Canon 50mm f/1.8 on the Canon M50, does it: Make my focal length effectively 35mm like a preferred street photography lens like on a fujifilm x100V? How does this work in regards to the crop sensor? Essentially we are given a non cropped image from the Canon 50mm, i.e. a full frame image? I'm getting confused with the 35mm image/focal length vs the full frame non-cropped image. Is going from 50mm to 35mm achieving the wider field of view, giving us a NON-cropped image, however this image is squeezed onto our aps crop sensor.
To better reword this: Using viltrox speedbooster on a 50mm on the Canon M50, are we getting a non cropped 50mm full frame image, or are we getting a 35mm image on a cropped sensor - or are these two essentially the same thing?
@@drunkntigr Essentually it is the same thing, the focal length is basically the same (however, on a 50mm on a cropped sensor, it becomes more like a 56mm uncropped since it is 50mm x 1.6 (crop factor) x .71(speedbooster) and this applies to all lenses). Hope this makes sense.
@@markwiemels It's strange some manufacturers do this. Canon will do the 22mm EOS-M lense when it is actually 35mm on the APS crop sensor (is this correct?), whereas Ricoh GR3 call their 28mm a 28mm equivalent.
Liked and subbed 👍 Just got an EF M-2 mount adapter but it's not compatible with my canon m50. Did I miss something? Any help would be much appreciated. Thanks
I have the speed booster & it’s def harder to focus and needs to be on a tripod almost all the time cause any movement even the tiniest will make the image blurry, if anybody has any suggestions I’m open to trying some out
This is likely just the shallow area that becomes in focus with the speed booster. From a movement perspective, looking at camera shake, the speed booster allows you to achieve higher shutter speeds, so should be even less prone to camera movement than the adapter.
A complete guide for speed booster for song zv e10 camera. Vlogging test . Auto focus test . Please make a detailed video. No video available on TH-cam sir.
I recently read a comment (not on yours) that the Viltrox adaptor has a shiny black surface on the inside which bounces stray light on the sensor. I have and use both the VILTROX adaptor and booster and the interiors of both are matt and I've never experienced the light flash he described have you?
Just got an R10. I'm using mostly for action sports indoors (i.e. basketball, volleyball) where I've found it difficult to get proper lighting. Would you suggest the booster for increased lighting? thanks and sub'd
Hey Mark, I've seen a couple of your videos and i have to ask after watching this video. Does the speed booster/regular adapter have an impact on autofocus performance and optical performance I'm planning to buy an m50ii and pair it with the sigma 18-35 1.8 and 50-100 1.8. your thoughts?
Adapter has no negative impact, the speed booster does impact image quality, and can effect focus performance. The 18-35 is a crop lens, not designed to work with the speed booster.
After reading all of these comments I feel kinda stupid! Lol. I only use my canon m-50 for recording vids & taking pics for holidays. I have a wide angle lens & a bigger lens I bought as an international version. I bought my canon as an international camera, too, & love it. I got the white one. A lot of this info is foreign to me. Very good explanation of the speed booster, tho. Subscribed.
I know that video is a year old, but I think there is something misleading here. Yes, in mathematical terms, you are right, but in practicality, I don't see the advantage. I have both using Tamron 18-400mm on Canon M6 Mark II. The widest (18mm) with a speed booster, may give you a true full frame of 18mm, but by the time you finish cropping (Cause you see the edge of the booster in the frame) you end up with practical 29mm (On Canon APC-S) As to the 400mm side, you get true 400mm, but you lose the cropping factor that gives you 640mm with the adapter which you can simply achieve by zooming out. As for light, I actually get a much noisier image with the booster so I don't really see the point. Saying that "you get two different focal length is misleading if you really expect to get a full frame image.
@@markwiemels After looking into it I realized that yes, you're right, but this is quite confusing since the mount is EF which is a full frame mount and not specified as EFS made for APS-C
Your comparison of 600% crop with or without speedbooster is not fair: since the speed booster gives a larger angle of view, fewer photosites are involved in the image of the head of the fish than without speedbooster. So you compare 2 images with a different number of pixels, that's why the head looks blurier with speedbooster !

I actually cut the plastic EFS mount off of my EFS 10-18mm lens so I could use it with the speed booster on my Canon M6-II and it works GREAT for video when I need a wide angle.

Thank you for this explanation ❤ I used a 50mm lens with the adapter on my Canon M50 Mark II last night for some astrophotography and was so confused as to why the image appeared so zoomed in / cropped. I think I understand why now after watching your video. So thank you!
Hi Mark, I had to revisit this video, after some time, as I was unsure of which way to go the first time around. Having taken the time to review the options, and rethink about what I was looking for, it's the adapter I want, not the speed booster. I am not looking to change my M50 ii anytime soon but wanted to consider the EF & EF-S lenses for their quality. Too bad Canon abandioned us M series owners. Lesson learned Canon. I'll be buying used. Thanks for your info and clear presentation.
thank you - i have a Blackmagic with 25mm lens but the crop factor is too much...i would like a Wider field of view ...hope the booster will help me - nice video thanks for making it...
Which one would you say is best for shooting beauty content or vlogging? Thanks
I watched your last video, thank you so much for giving us your opinion and all of this information, this will be my first time using a "professional" camera after wanting one ever since graduating High School and your videos are in very helpful for me to understand the photography world. I wish you the best!
Thank you so much for this clear, concise explanation! Just ordered a speedbooster along with a 50MM lens for my M50. Very excited to try it out after watching this!
You are most welcome.
@@markwiemels Have you noticed that the auto focus is significantly slow with this set up? I love the quality while its in focus...but auto seems pretty unreliable as of right now. Im wondering if its something on my M-50s end, or if its the speed booster/50 MM on their own.
@@markwiemels I shoot video, auto focus is pretty important :(
@@PatrickCrawfordVideo I mostly use the speed booster when taking photos, so can’t really comment on the video side. It seems fine for photos.
Most of my lenses are EFS or M lenses. My only EF lens is the 50mm 1.8. No need for the speed booster for the 50mm lens, since I have a Sigma 30mm 1.4.
So…I just use the Viltrox non-speed booster adaptor.
Yes, thats a good lens set.
Finally the video I was looking for. Thanks for taking the time to put this together for us. Thumbs up 👍🏼
So Good to hear! Thanks!
Thank you for this video - almost went with a speed booster but only have EFS lenses so that would have been a huge mistake. Appreciate the info!
I personally only use the speed booster with the canon 50mm 1.8, and that’s it. I think it’s great honestly and I can’t tell a difference in image quality.
I do have both adapters though, both from Viltrox. I use the regular adapter with my Sigma 18-35mm!
Those the are the lenses, and the way I use them too. Hard to bead the Sigma 18-35mm.
I want to buy my first camera for photography and I decided to buy the m50 mark ii, how’s it going so far from you? I’ve realized the kit lens isn’t too great so I’m going to buy the 50 mm f/1.8 lens.
Thanks for this review. I don't mind if it gives my pictures a more vintage look.. I have a Yongnuo 35mm F2 lens I use on my 90D and R7 and its sharp, but nothing compared to a Canon 35mm. But I love the look and its one of my absolute favorite prime lenses. Just give my images a unique vibe
I was just thinking about this I don't have any EF or EFS lenses but I may eventually move to a full frame camera and would invest in those lenses. I plan on sticking with Canon. I have a friend that is a professional and has lots of Canon lenses I could borrow so I may get both starting with the regular.
Yes, if you plan to move up to a RF camera at some point, the EF lenses make a lot of sense,
I'm a pro potographer and looking at buying either an M50 or the mark II for street photography, I do quite a lot of night time street photography. I've been looking at the spec's and cant really see a lot of difference, I already use full frame canon cameras. Could you tell me is there any major difference between the two, please?
Thank you so much for this informative video!! Answered all my exact questions I had.
I have a m50 mark 2 and with the speedbooster and a low light lens what higher priced cameras would it be equivalent to when decked out? Also a few years down the road I want to upgrade to a 4k/30fps full frame low light camera what would be the best priced camera? Im gonna get used so the cameras around now will be what im getting in a few years to save money.
Why would I do buy a speed booster? Because of the crop factor. Easy to answer. IF I want to use a 11 to lets say 24 mm prime lens, I have no other option. Sadly. Especially not with a good f-stop and auto focus. I wish there would be lenses that have ultra wide angles to counter the crop factor. But there aren't.
First, let me say thank you for this video because I watched some of your other videos and you mentioned a speed booster and I am new to cameras so I was like what is that and then I see this video so thank you so much for making these videos.
For beginners and budget user. Get both! Imagine that you get a cheap lens with F4.0, you can get aperture F2.8! For cheap!
I have a canon t7i and a kit lens and a canon 50mm 1.8 lens which one is better to film beauty makeup videos and would I need an adapter or a speed booster?
Hi Mark - so would the booster essentially turn a EF-M 11-22mm into a (rounded up) 8-16mm lens, with the bonus of having it a few f-stops lower increasing the overall aperture? I like the idea of just having to buy the booster without buying such an expensive lens for the same result, as a wide aperture, zoomable lens with a decent range is very pricey. So I wouldn't mind a small degrade in quality if it meant I can achieve a slightly wider FOV as well as having a few f-stops lower.
The speed booster adapts EF lenses to work on EF-M cameras, so doesn’t work on EF-M 11-22mm, but other than that yes, wider field of view and larger aperture (more light).
Hello 👋 ! So I have a m50 ii , I was thinking to buy a tamron 24-70 f2.8 g2 , the question its what you recommend : speed booster or adapter ? Thank you 🙏
Great video, but do you recommend me to buy the speedbooster and then buy 50 mm canon lens or do you recommend me to buy a Sigma 30 mm or viltrox 23 mm 1,4?
The image quality out of the 23mm and 30mm will be better. Have a look at my best prime lens video, it will help you choose the focal lengh. Be sure the watch the start of the video.
@@markwiemels can you please tell me the title of the video I should check from your channel? Thank you in advance UPDATE: I already found it and I am watching it.
My guess is, that if you achieve the same reproduction size on the sensor, the bokeh wont be different, but the sharpness would be better without the speed booster.
I think the physics are that with the speed booster you can get closer to the subject, because of the wider field of view, and this is what gives you more blur… I think..
Thank you for going into such detail. Extremely useful stuff!
This solves some questions i had 😅 I have a m50 mk2 with a 24mm f2, 50mm f/1 and 70-200mm f2
👍Thanks for the explanation, got the concept behide, I'm gonna buy both adapters
I'm so glad it was helpful! Thanks.
Great video Sir! Just bought a viltrox adpter for my canon m50 mark2, can i use my friend nikon d90 kit lens using this adapter? Thank u very much!
Bought both of them...depends on the shoot you want to have and the kind of lens you have or you want to use....both of them are from Viltrox....
Yes, I think that's the way to go.
@@markwiemels Better if you buy both from the same company so you can make the comparison between both adapters...
Hi can you recommend the best speed booster and adapter for the Canon 90D Thanks!
There is no EF adapter for that camera.
I'm still confused. So I am an aspiring real estate photographer. I have a Canon M50 Mark ll. I bought a EF-M 11-22mm F4.0-5.6 IS STM Lens. Because of the crop factor of 1.6 my 11mm becomes 17.6mm. IF I get a speed booster will I have a larger field of view more accurate to 11mm or 12mm?
We need both because the speed booster does not support ef-s. I use the speed booster for the nifty fifty. It makes it act like f 1 .2 instead of f 1.8
Good point.
Ok this makes total sense. You are the best! Thank you!
I beleive you are wrong about speed boosters always reducing resolution. The speed booster does need to consider the lens design. A well corrected lens is going to send the light to the sensors in cones with points st the sensor. The speed booster only needs to increase that angle and it is the same range over then entire frame, regardless of the lens focal length or aperture.
If the original lens has aberrations the speed booster may make it worse but I have used speed boosters on my Nikkor 180mm f/2.8 AI and it still out resolves my APS sensor.
My experiencxe is that these work very well on very good, sharp lenses at full aperture..
I'm definitely a speed booster kind of guy. I love the video quality
yes, it's a pretty cool look.
Oh boy, imagine the speed booster for Fuji X-Mount. I really want to have my SONY E lenses on my XT-1
Another great video! I was waiting for you to do one about the speed booster.
Good to hear! Thanks!
Hi I just bought the sigma lens you linked for m50 but it seems like I may need an adapter as this one is for Sony. Which adapter would that be?
Which lens did you buy? I will check the link, sometimes Amazon changes things. You can't adapt Sony to Canon
@@markwiemels The 16mm 1.4 you have linked goes to Sony. Ok good to know I’ll have to return that one thank you for getting back to me
Amazing content with precise details. Thanks for guiding.
Great to hear. Thanks.
Really like your explanation. I'm thinking of buying the adapter
Thanks.
Hello, excellent video! Question: I have an excellent Nikkor 50mm 1.2 lens I want to use on my M50. I got an adapter for Nikkor to EF-M but the crop factor is to big. What would be an effective way to fit than lens to my camera in all "full frame glory", so to speak? Thanks!
Thanks you men, really appreciated for this information. You deserve a lot 📈
Thanks!
I have an EF 75-300mm with Viltrox speed booster should I invest in the EF-M 55-200mm... Thoughts?
Only if you need the image stabilisation.
Brilliant and informative video yet again Mark. Really want to get the "Sigma 100-400mm f/5-6.3 DG OS HSM contemporary lens for my M50 mk ii (with the ef-m mount adapter of course) for wildlife and surf photography. The performance on an APS-C with an adapter should maintain similar image quality right? Thanks mate
Yes, I believe that would be a good setup, and sports and wildlife specialist oft keep a full frame body, and APS-C body, specifically to use that crop sensor reach. So that lens probably gets used like this all the time.
@@markwiemels sounds great! I think my decision is finally made to buy the lense. Thanks Mark and keep up the great work with your videos 👍
0:23 I mean most of these optics have too many elements anyway so adding a extra element that is good quality isn't going to hurt.
So clear thanks a lot, I love the exemples and you so clear
You are most welcome.
Hello, i have a m50, and i'm planning to buy the 55-250 or 18-135 EF-S lense, should i buy the speed booster or adapter?
adapter, they wont work properly with the speed booster.
Do they make a speed booster for the Canon EOS R7 and R10?
I have a M50 mark II. I recently purchased a speed booster. However, when I use it with a Tokina 11-16mm lens I get vignetting on 11-13mm focal lengths. Is this normal or a defect? Do I need to change a setting to remove the vignetting?
That’s an APS-C lens, the speed booster takes a full frame image and squeezes it onto the smaller sensor. So essentially that lens and the speed booster are not meant to go together, so yes, what you are seeing is normal.
so if i were to buy sigma 18-35/1.8 DC HSM CANON and mount it to canon m50 mark II... then should i get a speed booster? that's gonna be my first youtube setup so sorry if u are get tired of those questions.. - would really really appreciate ur recommendation! (just need a wide lense cuz sigma 16 f.14 turnt out to be to narrow for the small room i am shooting at)
Question for you. I have a M50 and a collection of 5 EF-M glass. I'm just a photographer with no EF lens. Do you think its worth it to start investing in a speed booster, Adapter and EF glass or in the long run just better to go with a RF second camera like RP and/or R7? PS I do want a second camera. The question is over the value of delaying getting a second camera.
The EF lenses do allow you to use them with RF cameras, and they are more affordable than RF lenses. RP is a lot of camera for the money, I’m a big fan.
Buy lenses for a need not as an investment. If you need a new lens you might consider adapting EF lenses for future compatibility.
Of you go to EOS R later then you likely want to buy RF lenses so the EF lenses would be a compromise.
Just got the sigma 18-35 and gonna get the adaptor for now. Great vid man tho
Great setup.
Hi, for canon m50 mark2, which is best buying efm lenses with high price or buying ef lenses with adapter in budget ?
It really depends on the lens, but I wouldn’t hesitate to buy more affordable EF lenses and use the adapter, you will get great results.
Will the Viltrox Speed Booster work for the Canon M50 with a Laowa 9mm f/2.8 manual focus lens for Canon ef-m mount? I'm trying to get more light in and wider 4k shooting real estate. Thx!
just buy both. I got my adapter today. Later I will buy speedboster
What is the question in the video even supposed to mean? If you wanna buy full frame glass, then you use the speecbooster. If you wanna use APSC glass then use the adapter. That's what they're designed for. Am i missing something?
Yes, you can use FF glass with or without the speed booster. The speed booster gives you a wider field of view and more light, at the sacrifice of image quality and detail. So that is the choice, and trade-off, that is being made.
@@markwiemels Right, but if you'd plan on using a FF lens with the adapter instead of a speedbooster then you might as well get the apsc equivalent of that lens instead. It's gonna be cheaper and smaller. So getting FF lenses to then just put them onto an adapter seems counter intuitive to me.
@@toastbrot97 That's not an unreasonable way to think about it, but it's not quite as simple as that. i.e. the very popular EF 50mm f1.8 does not really have a comparable APS-C lens at the a same price point. So it's not quite a 1:1 thing. None of the FF options will have an exact APS-C match, even though some may be close enough. Plus the speed booster on f1.8 FF gets you a f1.2 equivalent on APS-C, but with some sacrifices.
Hello Mark, the Artisan plain adapter coming from China is a reliable one?
really helpful! thanks for making this video
Glad it was helpful!
A lot of lenses are sharper in the center than in the periphery. An adapter will crop off the periphery effectively giving you a sharper image than on a full frame camera. An ideal adapter which introduces no distortion will preserve the peripheral distortion of the full frame lens. Real life lenses will of course introduce transmission effects.
Adapters don't modify the image all all. The smaller sensor just sees less of the image (a crop form the middle).
Great video and it explains a lot! But I do have one question and I would be happy if you could help me. I plan to buy 18-400mm F/3.5-6.3 Di II VC HLD which is EF lens but designed for crop sensor. Will speedbooster work with this lens or should I use the adapter? Thank you!
Adapter.
Why don't they make a higher quality speedbooster?
Thank you so much, one of the most realistic reviews. Cheers
Great to hear!
Bought the Viltrox Speed Booster M2 off your affiliate link ;). Question though: Using it with a Canon 50mm f/1.8 on the Canon M50, does it:
Make my focal length effectively 35mm like a preferred street photography lens like on a fujifilm x100V?
How does this work in regards to the crop sensor? Essentially we are given a non cropped image from the Canon 50mm, i.e. a full frame image?
I'm getting confused with the 35mm image/focal length vs the full frame non-cropped image. Is going from 50mm to 35mm achieving the wider field of view, giving us a NON-cropped image, however this image is squeezed onto our aps crop sensor.
To better reword this:
Using viltrox speedbooster on a 50mm on the Canon M50, are we getting a non cropped 50mm full frame image, or are we getting a 35mm image on a cropped sensor - or are these two essentially the same thing?
@@drunkntigr Essentually it is the same thing, the focal length is basically the same (however, on a 50mm on a cropped sensor, it becomes more like a 56mm uncropped since it is 50mm x 1.6 (crop factor) x .71(speedbooster) and this applies to all lenses). Hope this makes sense.
@@wubbadubnub Cheers
Yes, this is correct, very close to the same field of view.
@@markwiemels It's strange some manufacturers do this. Canon will do the 22mm EOS-M lense when it is actually 35mm on the APS crop sensor (is this correct?), whereas Ricoh GR3 call their 28mm a 28mm equivalent.
Maybe a stupid question, is there a speed booster that works with the eos rebel T5 / eos 1200D ?
I have both of them. The Viltrox speed pooster and the adapter.
Good setup.
Which one do you recommend for m50mii with a macro lens for dental photography purpose?
Is this lense compatible Canon RF 35mm f/1.8 IS Macro STM
For canon m50 mark ii, if you have an adapter?
wait! I can still use ef-m to ef-m+efs lenses? Am I getting that correct? or do I need to buy multiple?
help.
Liked and subbed 👍 Just got an EF M-2 mount adapter but it's not compatible with my canon m50. Did I miss something? Any help would be much appreciated. Thanks
The names are confusing M2 might be the Sony to EF, or Panasonic to EF. You need the EF-M to EF.
Are there any budget 14-16mm lens that can be added to the viltrox speedbooster to give a nice full frame when recording in 4k on the m50 mark ii?
Not that I am aware of.
Just the information I'm looking for. Thanks
I'm so glad it was helpful! Thanks.
I have the speed booster & it’s def harder to focus and needs to be on a tripod almost all the time cause any movement even the tiniest will make the image blurry, if anybody has any suggestions I’m open to trying some out
This is likely just the shallow area that becomes in focus with the speed booster. From a movement perspective, looking at camera shake, the speed booster allows you to achieve higher shutter speeds, so should be even less prone to camera movement than the adapter.
Another classic brotha, thank you!!!
My pleasure!!

No video available on TH-cam sir.
Good idea. Thanks for the heads up.
@@markwiemels please make a video fast .
I recently read a comment (not on yours) that the Viltrox adaptor has a shiny black surface on the inside which bounces stray light on the sensor. I have and use both the VILTROX adaptor and booster and the interiors of both are matt and I've never experienced the light flash he described have you?
I have had this reflection issue with the genuine canon adapter, but not that Viltrox.
Does using the adapter create a zoom effect with an EF lens? If so how much?
no
Can you please suggest a speed booster to convert from nikon f to sony e apsc.
Just got an R10. I'm using mostly for action sports indoors (i.e. basketball, volleyball) where I've found it difficult to get proper lighting. Would you suggest the booster for increased lighting? thanks and sub'd
Yes, that will help for sure. It's hard to know if the sacrifice in image detail will be an issue or not, you would really have to try it out to know.
Hey Mark, I've seen a couple of your videos and i have to ask after watching this video. Does the speed booster/regular adapter have an impact on autofocus performance and optical performance I'm planning to buy an m50ii and pair it with the sigma 18-35 1.8 and 50-100 1.8. your thoughts?
Adapter has no negative impact, the speed booster does impact image quality, and can effect focus performance. The 18-35 is a crop lens, not designed to work with the speed booster.
After reading all of these comments I feel kinda stupid! Lol. I only use my canon m-50 for recording vids & taking pics for holidays. I have a wide angle lens & a bigger lens I bought as an international version. I bought my canon as an international camera, too, & love it. I got the white one. A lot of this info is foreign to me. Very good explanation of the speed booster, tho. Subscribed.
Thank you so much!
I know that video is a year old, but I think there is something misleading here. Yes, in mathematical terms, you are right, but in practicality, I don't see the advantage. I have both using Tamron 18-400mm on Canon M6 Mark II. The widest (18mm) with a speed booster, may give you a true full frame of 18mm, but by the time you finish cropping (Cause you see the edge of the booster in the frame) you end up with practical 29mm (On Canon APC-S) As to the 400mm side, you get true 400mm, but you lose the cropping factor that gives you 640mm with the adapter which you can simply achieve by zooming out. As for light, I actually get a much noisier image with the booster so I don't really see the point. Saying that "you get two different focal length is misleading if you really expect to get a full frame image.
That’s an aps-c lens, not full frame, that’s why you see the lens. The speed booster is for full frame lenses.
@@markwiemels After looking into it I realized that yes, you're right, but this is quite confusing since the mount is EF which is a full frame mount and not specified as EFS made for APS-C
@@ziv2liv Agree it's confusing, I think Sigma call it an EF lens for APS-C cameras. Where Canon would call it an EF-S lens.
Your comparison of 600% crop with or without speedbooster is not fair: since the speed booster gives a larger angle of view, fewer photosites are involved in the image of the head of the fish than without speedbooster. So you compare 2 images with a different number of pixels, that's why the head looks blurier with speedbooster !
I moved the camera to compensate. So the framing is the same, as is the resolution used.
is it work on a sigma 16 mm lens for canon m50 mark ii
Your review is just amazing!
Thank you so much!
