Thank you for this. Yours is the only video I’ve found so far where someone has actually tested the canon adapter with the R7 and isn’t just speculating.
it does give you shallower depth of field, look at your shoots at 1:27. You are getting the same bokeh at a wider FOV therefore if you recompose with the adapter the bg will have more blur
I believe the correct explanation is: It will give you similar bokeh to the lens set at 2.8 when mounted on a full frame camera, and the extra stop of light, taking it to 2.0. But it won't give you the bokeh of a 2.0 lens.
No it’s exactly like a f/2 49mm lens Just the opposite of a TC (focal length extender) this is a focal length reducer which shortens the focal length whilst the front entrance pupil is unchanged This alters the f/ stop F stop = focal length devided by the entrance pupil diameter
@@BobbyD262 Bokeh, shmokeh. The real beauty of this setup (I think) will be when paired with a lens like the Sigma 14mm 1.8 for astro. I'm looking for any excuse to dump my R5. The only other factor for me would be the 120p diff between the R5's 4k and R7's 1080p.
As Ángel said here. If here were to match the framing (by moving the camera forward since he gained more FOV) you would gain more DOF (the one of a 2.0) So if you grab an R6 w/ RF 24-70 2.8 vs an R7 w/ EF 24-70 2.8 on a speed booster. The R7 would have more DOF
Maybe the first review of R7 with speed booster. I am interested in R10 hop this works fine. Please do detailed review including image quality, sharpness.
I always recommend BUY 2 of the same because in the heat of the photoshoot, every button is the same, and there no need to mentally change the way you work. WHEN the equipment becomes ONE with you then you can really do some serious work.
good remark: I thought about ONE R5 C but it is expensive if you want two of them and lacks the IBIS (for my use cases). Maybe the R7 + R7 C are a great combo if, yes, if Canon keeps the layout VERY close together.
Thanks for confirming that this focal length reducer works fine! I ordered the R7 and I am interested in using a 16-35 mm lens on the R7 with that adapter or the f/2 100 mm. And a really funny solution with the red circular stickers on the adapter - I HATE the well hidden red/white marks and fiddling Canon has introduced with the R mount. Including the loss of the old three position-mounting of rear caps. Not everything is getting better but the DPAF and the in-camera-software behind is a revolution on its own. So I will do the sticker trick like you!
Thanks for the review, I took a risk and bought this few weeks ago used (in 5/5 condition) for €250 and now I see that my risk taking is probably paying off, I'm still waiting for my R7!
I believe this is the Canon 7D iii people have been waiting but Canon decided to go mirrorless. Look forward to seeing more reviews of this camera, like "After 6 months of use", or "After 12 months of use", and or "After 4 weeks of use".
I strongly think this R7 is going to be the hidden GEM. Same sensor almost as the R3, 30.2 mp I think for this APS-C? It's geared for action sports and wildlife but can do other things. Another gem Swiss army knife for only $1499..
@@joaomansano145 Think about 1 to 2 years from now, buy this used, it will be the same as the 90D ( another Swiss Army knife ) which is around $1,000. And 5 years from now if I'm still alive or we're still alive, I predict around $600-$700+..used and that would be A STEAL!! .
Interesting video but the camera is showing correct exif data as this is a focal length reducer which is the opposite of a T.C (which is a focal length extender) so it really is f/2 and 49mm just as when you add a 1.4x T.C it would become f/4 and 99mm. Bokeh and depth of field will be the same as a 49mm f/2 lens. I'd love to try this out with my EF400mm f/2.8 which would make it a 283mm f/2 and my EF300mm f/2.8 for a 212mm f/2 It's a very expensive accessory though at (USD)$600 plus the $1500 for the R7 equals $2100 which isn't much less than an R6 so if you want full frame possibly better to spend a bit more for the R6 (plus you would want a normal adapter which is another $100 for a total of $2200) On the other hand with the R7 plus 071x reducer (and normal adapter) and EF lenses it's almost like having 2 cameras
I haven't seen anything that indicates anything special about the Canon branded speed booster other than it fits more snug than the Viltrox. I have both the Viltrox and the Metabones and they seem to work just fine. Also haven't ever gotten the message about possible incompatible accessory with either of those speed boosters.
I’m wondering, why you said that with the speedbooster you don’t need to expect the bokeh difference… cause I definitely do have a better bokeh while using the speedbooster+full frame lens combo. Yes, it’s still not as good as the full frame body+lens combo, but it’s still much better than the one without speedbooster. Btw, lot of people don’t really realise that speedbooster is specific tool that must be used in certain situations while you really need this extra stop of light. Same thing like with the extenders. It’s really worth mentioning that it’s not the way to make crop sensor camera work like full frame. PS. Thanks for short review, it’s gives people basic information about the tool and it’s needed to be done. Lot of information that can be found about speedboosters in TH-cam today filled with misleading information and new hobbyists just can’t realise if they really need to buy one or not.
F2 shown for that lens is relative to a crop, which is exactly f2.8 in full frame terms. It was F4 on a crop without the speedbooster though. Yeah, it's confusing, and we can thank to camera manufacturers for lying about apertures on crop bodies :)
f2 remains f2, there's no lying. The perceived depth of field is less shallow because of the sensor size, but the aperture remains physically the same.
Hey man thx for this video! Can u talk about the IBIS w/ the speedbooster? Works fine?! I saw other video where the guy can’t put it to work but was a viltrox version
Interesting test, thanks for that! I see you have an extra rubber ring on your Canon EF-S 17-55. Can you tell me where you've got that from? My focus ring is sticky and looking for just such a ring to put over it.
Hi, thanks for the comment. The rubber ring came with my Peak design Messenger bag. But maybe u could use follow focus rubber ring from Tilta or SmallRig.
Bokeh is the blurred-out background - If one were to frame the subject matter with the same proportions, with and without the adapter, then because of the wider field of view with and the adapter one would need to be closer to the subject for the same framing. Being closer to the subject would create more background blur - increasing the bokeh. There is no added bokeh when cropping in on the image, but there is when reflaming the image.
So using focal reducer gives wider fov, 1 stop brighter image, but the DOF stays the same? Would have liked more bokeh for C70 + Sigma 60-600mm sport combo.
Thanks for this video. I plan to buy this speedbooster. Do you need the 4 screw mounts with this speedbooster? Although it might give tight secure fit, i believe it would be annoying to take on and off for other lens. It seems like youre not using the side mount screws. Let me know if it's worth it. Thanks.
Hi, I haven't done any real video work with the r7 yet so I can't really recommend one over the other. There are still some tests I need to run, e.g how does it perform with Ninja V. R6 has two shortcomings when paired with Ninja that really bother me. The r6 has really good 60p though, so if you shoot a lot slo mo the r6 has an advantage. I will keep posting my findings.
The R7 has the new digital hot shoe which, combined with the new TASCAM canon xlr ca-xlr2d will be a big advantage in the audio capture side. A concern would be if the R7 would play nice with third party dummy batteries that would allow it to be powered via d-tap.
Nice, I’m recently interested in this combo since I have a few EF Full frame lenses. I think the issue now is how do we update the 0.71 adapter without the Cinema camera. I understand there was a firmware update for it recently…
Does the speed booster at least bring the lens back to looking like a 2.8 lens on a full frame? That would be the only reason I would want to use one I think is if it made the crop sensor image look very much like a full frame image with shallow depth of field and soft background.
I don't think it is worth getting this speed booster for any EF-S lens, depending on a focal length you will get strong vignetting in the corners. For the price of the canon speedbooster you could find the excellent sigma 18-35mm 1.8 which provide much better pictures, video than any EF-S lens with speed booster.
Interesting point, I will check this weekend. But the problem with 17-55 for video is that it has very noisy AF that sounds a little like grinding.You need anexternal audio recorder.
I did try it on the r7 and it worked well. I used to have one with Nikon d500 but it had problems with back-focusing. Now with mirrorless this lens can really shine.
when using the speed booster, how is the auto focus? are there any known issues or noticable to the eye problems such as vignetting, chromatic abberations, softness (not sharp) footage/photos etc? (not minor absolute problems that exists only on lab tests but are not noticable to the eye)?
The AF works fine. Depending on the lens there are some problems with a purple circle in the middle of the frame at wide focal length. The same problem is reported by Canon c70 users. I will try to make a video to show some examples of the speed booster with Full Frame lenses.
Is there eny light bleeding Los contrast or ibis problem caused by the speed booster ? There's a viltrox version too its more affordable how is that compare to the canon one ?
I haven’t encountered any of these but I need to do more testing in different light with different subjects. Can’t comment on the Viltrox since I don’t have one but it may be a better option considering the price.
Can you confirm if the electronic apeture control works from the camera? I see you showing it does the math, f2.8 displays as f2.0. Can you close the apeture to f5.6? It shows f4.0 then?
It won’t work with the sigma 18-35 though, after the speed booster the image circle won’t be able to cover the whole sensor. You’re only supposed to use full frame lenses on a speed booster for APSC cameras, APSC lenses should just be adapted directly without the speedbooster
@@DavidKabra Hmm that’s interesting, most reviews I’ve seen there’s still visible vignetting at that range if you try to use it on full frame. Do you use a speedbooster on the M50?
@@DavidKabra Maybe in crop mode on the R :) You could use something like 30mm+ on a full frame, but the only point of that Sigma is range with a wide aperture, and it becomes a prime when you put it on full frame, which kills it's main purpose.
I dont have much joy with adapters and extenders..that extra glass in front would at some point diminish the pixture quality. Maybe I should rent one first to try..
I have a question. If the speed booster essentially makes the field of view wider, if I was to move myself physically closer to the subject to get the same Field of View that I would have got without the speed booster, wouldn't that essentially increase the Depth of Field?
@@juliankrakow thanks for posting the link, the one you have posted appears to be the Canon EF RF adapter, but not the speedbooster 0.71, can you add that link too ? Is it a Viltrox ?
@@AZguy2024 It shows the proper link on my side. Canon Ef - EOS R 0.71x. I don't have the Viltrox adapter only the regular Canon EF - RF and EF - RF 0.71x (speed booster - is not official name)
thanks for this video! when filming 4K with the speed booster can you film at 50/60 fps? or is it reduced to 25/30fps? because from what I heard, the original EF-RF lens adapter you get when buying the R7 restricts 4K video to 25/30 fps (is that correct as well?!)
I guess it comes down to what do you usually shoot and if you already have FF lenses. The r6 has better 60p and the r7 better AF. Personally I got the r7 as a second body and if I was keeping just one I would keep the r6. The Canon speed booster is quite expensive and unless you can use it together with C70 or other cinema camera I don't think it is worth just for the r7.
Amazon: Maximum Focal Length 105 Millimeters Minimum Focal Length 16 Millimeters does that mean it can't work properly with 70-200 on focal lengths longer than 105?
ciekawe jak duża jest różnica w ogniskowej między nagrywaniem 4k w r6, a r7 ze speedboosterem, ciekwe też czy te slowmo z r7 jest lepsze od r6 (chodzi mi o 100kl w fhd) wg. liczb to speedboosterowy crop to jest 1.13 troszke większy niż r6 bo tam jest 1.07, teraz pytanie, czy wymieniać R6 na r5 czy dokupić r7
Hey, nie testowałem jeszcze 100p więc niestety nie mogę się tu wypowiedzieć ( na razie za dużo innej roboty). Kupiłem r7 jak drugą puszkę ze względu na fotografię. Ale gdybym zarabiał głównie na wideo a nie na zdjęciach to wziął bym r5. R6 i R7 raczej się powielają a nie uzupełniają w wideo. Mają te same ograniczenia jak się je podłączy do Ninja V. R5 to mimo wszystko inny poziom jeśli chodzi o użyteczne funkcje wideo.
No, the f number changes as well because the focal length changes. What doesn't change is the effective diameter of the lens. Smaller f-number doesn't necessarily mean that the effective diameter increases, that's not the definition of the f-number.

Still Waiting for my R7, hopefully soon will be with me.
0:16 what about R10, R50 and R100?
Not sure, the R7 is the only APS-C camera I have used
I have the Meike Speedbooster for the Canon R10. Works perfect.
does the adapter effect image stabilization?
Not in photo mode but I haven’t done much testing with video yet.
thanks for this video! when filming 4K with the speed booster can you film at 50/60 fps? or is it reduced to 25/30fps?
because from what I heard, the original EF-RF lens adapter you get when buying the R7 restricts 4K video to 25/30 fps (is that correct as well?!)
You can record at 60p with both the speed booster and the regular Canon Ef-RF adapter.
@@juliankrakow AWESOME! thanks!
좋은 정보 감사드립니다^^
Thanks. Please consider subscribing
So are there any benefits to buying an R7 + Canon speedbooster vs. just buying an R6 for a few hundred more dollars?
I guess it comes down to what do you usually shoot and if you already have FF lenses. The r6 has better 60p and the r7 better AF. Personally I got the r7 as a second body and if I was keeping just one I would keep the r6. The Canon speed booster is quite expensive and unless you can use it together with C70 or other cinema camera I don't think it is worth just for the r7.
Does IBIS work?
Yes, it does. (but somehow it seem weaker, having IS on the lens helps)
Amazon:
Maximum Focal Length 105 Millimeters
Minimum Focal Length 16 Millimeters
does that mean it can't work properly with 70-200 on focal lengths longer than 105?
My Canon 70-200 f2.8 IS III works with the speed booster without any problems.
@@juliankrakow that's great ! so any idea why they wrote "Maximum Focal Lengt 105 Millimeters?
@@NitsanArt Not really. I have no problem with mine.

Now put an extender on it! 🤷♂️
ciekawe jak duża jest różnica w ogniskowej między nagrywaniem 4k w r6, a r7 ze speedboosterem, ciekwe też czy te slowmo z r7 jest lepsze od r6 (chodzi mi o 100kl w fhd)
wg. liczb to speedboosterowy crop to jest 1.13 troszke większy niż r6 bo tam jest 1.07, teraz pytanie, czy wymieniać R6 na r5 czy dokupić r7
Hey, nie testowałem jeszcze 100p więc niestety nie mogę się tu wypowiedzieć ( na razie za dużo innej roboty). Kupiłem r7 jak drugą puszkę ze względu na fotografię. Ale gdybym zarabiał głównie na wideo a nie na zdjęciach to wziął bym r5. R6 i R7 raczej się powielają a nie uzupełniają w wideo. Mają te same ograniczenia jak się je podłączy do Ninja V. R5 to mimo wszystko inny poziom jeśli chodzi o użyteczne funkcje wideo.
What it gives you is a T stop of light because of the glass, not an F stop of light- the geometric aperture stays the same, does not open a stop.
No, the f number changes as well because the focal length changes. What doesn't change is the effective diameter of the lens. Smaller f-number doesn't necessarily mean that the effective diameter increases, that's not the definition of the f-number.
@@Quoutub correct.
f stop is a ratio number.
A lot of seasoned photographers still thinks its the physical diameter
how match cost sir
There are links to all prices in the description of the video.
You could almost buy a lens for the price of this
Used Sigma 18-35mm f1.8 would be my choice : )
