This is, BAR NONE - the best calibration video for a Sigma lens I have seen. Thank you for pointing out how to achieve the correct distance from the camera to the target using the lens' display window. If you have a Sigma lens, get the dock and follow the steps in this video. NO shortcuts!
I've been using this lens on a t7i and have basically just been manually focusing for the last year because the autofocus is so off. Thanks for the great video, this is super helpful.
Just purchased a Sigma 105 mm SA lens with a Canon USB Dock. I am reviewing all the tutorial videos to understand the calibration process. Absolutely excellent presentation! Thank you for your time and clear instructions.
Great video thanks! I have had the sigma 18-35mm art lens (Nikon fit) for over a year now. I have the dock but only checked firmware as even the thought of learning the process of focus calibration has tested my patience, but thanks to your video I think I will do it now.
Thank you, this is very helpful. I have been postponing the callibration process exactly because it was so intimidating. Now I know it is not that difficult!
THANK YOU! Exactly the information I was looking for, same Sigma lens you have and a Canon 90D. Subscribed just as a thank you for saving me the trouble of trying to figure out how to do this myself.
THANK YOU!
I have a Canon T7i and just tried your settings and it works FANTASTIC!
Appreciate the time and effort you have put to post this video its so helpful!
ALL THE BEST :)
Thanks Aaron! I just bought one so this is definitely helpful!
Thank you!! Cant wait to try this, all I ever did with it was update firmware with it.
Tip: the reason for the fold down section in the middle of the paper guide is that when you have that perpendicular to the lens and in the center on the view, you can autofocus on that flat surface instead of trying to focus on the 0 which is not perpendicular. The center part It is folded at the 0 mark for you. Then you look at your photo to asses focus you can then use the scale to the side to make your adjustments.
Great information. Thanks. A critical area with our cameras but technically tricky stuff
Outstanding!
Thank you for this. I was really unsure how to proceed until watching your tutorial
Thank you so very much. You explained this simply for me. I just bought a new (used) Sigma 150-600mm and I was completely lost on how to focus it.
Thanks
Can I use these settings eventhough I use a Nikon camera? The D3200. I have the same lens and found it is struggling with auto focus on viewfinder
hai, pls make video sigma 150-600mm c calibration tutorial plss especially with 90d canon body ..
helpful
Hello, question, after adjusting the distance at each focus point, you return to zero in the camera when the lens is already calibrated?
Do u own any gimbals? Im trying to hook up my t7i to a ronin s any help?
When i configure the focus for example 35mm, does this not influence what was already calibrated previously?.
Thanks!.
You did an amazing job with explaining the process. Have you heard about the dot tune AFMA method? its on TH-cam as well.
Great video!!! I'm having trouble with infinity. How did you manage to set it up?
Nice Sir
Do you know if you manually adjust the focus in camera without the dock would work?
Yes that would work, the dock is only for adjusting the autofocus in the viewfinder. If you shoot manual focusing or even in live view mode it's fine.
Useful tips, but that "calibrator chart" or whatever we may call it, it has to be used with that QR code part unfolded, it is meant to focus on that QR code with your lens, this is your focal plane and it has to be a perfect 45 deg angle with the ruler. Folding it, you actually are creating a false or slightly off focal plane which is resulting also in a much smaller target to focus on.
The way I do it works for me on multiple lenses, so I'm just showing how I do it. I'm not saying it's right, wrong, or the only way.
Can you do this in camera using the lens micro adjustment via auto focus sensor?
Not on the cameras I own. I'm not sure about other manufacturers.
This video was made for me I’m about to get this lens haha
Did it need calibrating out of the box? Just ordered one and i'm unsure if I need to buy the dock or not
Mine did, but for video it will be ok, also shooting photos in live view should be ok.
Hi, how did you calibrate the infinite setting if you don’t mind explaining. I calibrated my 24-105 at all the indicated distances (red lines in Sigma tool), but I’m wondering about infinity. If I put the calibration thingy at, say 100m, I might be able to focus on it, but there is in no way enough detail in that image to judge back or front focus.
I picked a roof in the distance and used air vent on the roof as my focal point and the shingles as guides. Lol. It was the best I could do.
Im pretty new to all this. Can i just copy your settings and have it be perfect? I also have the sigma 18-35mm f/1.8 and a T7i
Yes, that's what I'd recommend.
Thanks for video Aaron, great job. 👏🏻 But I wonder how could you set infinity focus and angle? 🤷🏻♂️
12-24 dg hsm art kullanıcısı olarak bu sorunun cevabını arıyorum aslında :)
As a 12-24 dg hsm art user, I'm actually looking for the answer to this question :)
hi. thanks for the video. on 0.35 at 18mm i have to calibrate it to 20+ and it's still slightly out of focus. i need at least another +2s to get it in alignment. Is this normal and do you know a way to fix it? thanks?
I've used max settings on a few distances before. Unfortunately it's not perfect, but i learned to use it and still get excellent results. It is very frustrating that we even have to calibrate in the first place.
Hello, you have the possibility to increase the global focus. I mean that you have two types of adjustment, within the fine adjustment section (in nikon and canon). One setting is the global one (which affects all lenses equally) and the other is the individual setting for each lens. I suggest you increase the global to +5 (to gain 5 steps) remember that this will affect other optics you have calibrated, so you should subtract -5 from each optic that needs it. I hope you find it useful!
Hello, I have the same setup as you with a canon EOS t7i camera body with the sigma 18-35mm 1.8 lens, do you think I’ll be able to copy your calibrated settings and the autofocus will be better?
It should, I've had a lot of people say it worked for them
@@FitsandFun sounds good! I will try it out :D
Great tutorial, thanks.
Where can I find your settings?
Regards from Sweden
17:10 are my settings
Hi Aaron. I have a Sigma DC 18-250mm f3.5-6.3 lens (with a Nikon mount) that I'm having trouble focusing with. I bought the Sigma UD-01 USB Dock, but after downloading the the Sigma Optimization Pro software, it told me that the software isn't compatible with my lens. I can't seem to find a different version of the software (or dock) that is. Any ideas on how I can calibrate this lens?
I have no idea, unless that lens doesn't have micro adjustment capabilities. I haven't had that problem, so no idea how to fix it.
@@danielle8622 Thanks - I did eventually figure out that the lens wasn't compatible with the dock, and ended up sending it to Sigma for calibration (it was still under warranty). I've since upgraded both the lens and the camera.
thats strange, for the same lense... my app tells me the latest firmware is 1.01... mine is the nikon mount though
Do you need these docks for the older generation sigma lenses? I am using the 24-70 and 70-200 f2.8 EX APO range (pre Art, Sport etc)
I don't know, I don't own those lenses. Sorry.
So, could I just take your exact settings and plug them into my 18-35mm and it would be okay, or are the numbers/settings going to differ for each individual lens?
It might be ok. A lot of people say it works.
Nice video. But I have 35mm, does that mean, that I have to move my target for every single distance, and do I have to do that on manual or autofocus? For example, if I want to calibrate 2m distance, do I have to put my camera on 2m of the target, and then 1m, do I have to move my camera again on 1m distance of the target?
Yes, there should only be 4 distances.
Can I use your settings on a EOS 90D? Greetings from Portugal
Yes, they should work pretty well.
Could you take all the pictures at once at different focal lengths and distances?
I'm sure you could, but I'm not sure calibrating and rechecking would be as accurate after adjusting the focal lengths and distances around.
Hi wouldn't you focus on the flat portion of the calibration kit? Would that not be the 0 on the ruler?
No, think of the slope as say the tip of a nose vs someones eye. They are different distances away, so the slope represents the depth of field, and using the zero on the slope allows you to pin point the depth you want your focus. So if you focus on the zero on the slope and the 1 is what is in focus, you'd really struggle to get someones eye in focus from that distance. So the slope is the key to calibrating the autofocus points.
hmmm so the flat portion is not the portion you focus on then? I assumed the 0 and the flat portion was the same thing. You would focus on the flat portion and take an image. Then look at the ruler to see if it was back or front focused.
I just ordered the same kit you are using off amazon for $5.50. I have noticed that my images aren't as tac sharp as I want them to be, I am guessing I am having front or back focus issues.
Which focusing metering system did u use for canon, I tried with evaluative metering not being able to focus on the spot
The metering mode should only effect exposure, not focusing.
It should be single dot focus with one shot, not ai servo.
@@FitsandFun thanks for the reply 👍
Hi, and thanks for your interesting videos, I have a question; when you do the calibration do you do in auto focus or manual focus ?
Thanks
Auto focus. The whole point is to calibrate the autofocus.
Any luck anyone on the 90D?
Two questions, how far away you put tripod to do infinity? And do you know why my black/white contrast look terrible including pink colour present?
Infinity is hard because I actually just used a neighbors chimney, the guide I have is way to small for an infinity adjustment. As far as the contrast, probably your picture profile, I'd recommend trying a different picture style/profile and see if that fixes it.
Hi, can i use this same setting on canon 80d ? Thank you...
Probably, it would be better than no adjustments, but it may need slight tuning.
@@FitsandFun thank you so much
Can this dock type calibration work for mirrorless cameras also or does only affect prism type DSLR's? My Sigma 24-70 Art lens is back focusing on my R5.
I don't think it would help on the R5. Because that's using dual pixel auto focus, the dock calibrates the lens to the viewfinder where you manually select the focus point and then calibrate to that specific point in the optical view finder. So two different focusing methods. Again, I don't think it would work, but I don't know for sure.
@@FitsandFun I was afraid of that. I hope either lens mfg's or Canon would come up with something. As I understand it, the camera and lens would have to be sent to Canon for calibrating. But they will only do it for Canon lenses. :(
The other option would be for you to make the slight adjustments during the photo, if it's consistent. Like recomposition.
@@FitsandFun True, but not exactly practical during live action and such. I sort of wonder if it has anything to do with using the EF adapter. The Canon EF 70-200 doesn't do it as bad, but I also don't have an RF lens to test with yet. The Sigma is really noticeable... :( Ill update this if I find out anything more about it.
I used 5d miii and how many stages do I have to calibrate my new 35mm f/1.4 Art lens ... I need a good procedure
You'd have to do all the distances. I think it's 4 times.
@@FitsandFun thanks for the swift response. I will do as you have advised and give you a feedback. Thanks
@@emmanuelowusu-prempeh2151 did you calibrate already your Sigma 35?Maybe you can give some advice pls?;)
th-cam.com/video/9jJOR3X4prY/w-d-xo.html
If you go to the 2:00 mark in this video I show the settings I use for my Sigma 35mm f1.4. They may work fine for you.
@@yuliannakhomych7619 please update the firmware of your Camera first and then update the firmware of your Sigma 35mm 1.4 art. And take some test shots and let's see
If I buy new sigma 150-600 yesterday that mean I must calibrate etc also?
I'm not sure about that lens. Not all Sigma lenses need to be calibrated. It will also depend on what camera you are using. So I'd always try the lens out first, and if you are missing focus often then you probably need to calibrate it. If it hits focus then it's fine.
@@FitsandFun i use 80D and yes,images are not sharpness etc (got problem even on 20mm yet)
Does anyone done this process for the 85mm 1.4? Please share it 🙏
i dropped my 85mm 1.4 dg dn and its not sharp at 1.4 :( everything its working well but the sharpeness sometimes its gone :(
👍👍👍👍👍
I didn’t know I had to do this? How much do they charge for this service I wish I knew before buying both sigma lenses
I agree, I didn't know either when I first purchased the Sigma 18-35mm f1.8. I don't know of anyone who does this as a service because it's unique to your specific camera body. But a lot of people just copy my settings and they said that it worked well for them.
Alright mate can I use those settings for 90d ?
They should
@@FitsandFun cheers and so you didnt calibrate this lense specially for 90d ?
Nope. I used the t7i
@@FitsandFun alright sound mate is there any chance that you could make a video to calibrate infinity on this lense ?
Thats a tough one to calibrate, i used something fairly far away on my house with a pattern. It was a pain, but I think it came out alright.
Let me correct you.
If your lens is BF back focus you need to bring it closer to 0 in the scale. Meaning you need to MINUS it so it come closer to 0 and not increase PLUS. otherwise itd be more back focus.
For front focus FF you are to do the opposite.
Awesome job, keep up the good work.
I was looking to see if anyone noticed this also, he literally said it the wrong way around, he probably meant to say that the lens is front focusing so adding +2 would fix that.
Isn’t that front focusing? Not back?
Just bought it for nikon and... Could not do it. Trying over and over. But adjustment just wont work
Did you sort it out?
What Nikon model you have ?
@@danfatu6549 the D3200
I think you are doing it wrong and you are sharing misinformation.
1) You should be focusing on the QR code, not the 0 mark.
2) Your camera doesn't seem to be at level with the target. If it was, your focus point should be exactly in the middle of the image.
3) At 6:03 you say you don't need measurement devices. Why? How can you calibrate a lens without accurately measuring the distance of the focal plane?!
4) Of course you didn't have anything off. You moved the target until it was sharp in the photo instead of fixing it at the calibration distance.
5) The red bars in the computer software indicate where the focus ring should be positioned. Don't look at the numbers, look at the bars!
This works for me, so I share what works for me.
Hi Aron, you espeak espanish ou portugaise? Please🙏🏽😰 not have video explication in ES, FR and PT :(
Why not just see where on your camera is located sensor mark likes like: ф and just measure the distance between sensor and target? This is the best way.
I did it both ways and had the same results. So I'm sharing the way I think is easiest.
Sorry but this is not what other videos explain about lens calibration. It's not about how precise the zero is, is about how equal the gradation is in terms of focus. The 1/2 in your experiment, should be the same amount of out of focus, which is not, because you emphasize on the zero. This is the same to just shoot a teddy bear and compare microadjustments till you see the eye in perfect focus, doesn't work that way, that's why the calibration kits have rulers.
Like I said, this is how I do it. And this works great for me. I'm not forcing anyone to do it this way.
You're doing it wrong. You need a ruler and then measure 0.28m from the sensor of the camera (there is a mark of that on every camera) to your object you are focusing on, than measure 0.35m and so on.
Worked for me
I don’t think he’s doing it wrong. This is basically adjusting where the autofocus lock thinks the lens is focusing vs where the lens is actually focusing. The actual distance from the sensor to the object is not critical... as long as you are in the ballpark of the scale for the four focus points in the sigma software you should be fine. Obviously the closer you are to the scale the better the calibration, but using the scale on the lens should work nicely and be much easier. You are not calibrating the distance scale in the window of the lens.
@@FitsandFun It worked because you were close, but Stefan is correct, it should be EXACTLY that distance from the marking on the camera body to the target.
@@dbauernf it worked, and that's how I do it. So I shared how I do it. I never said it's the only way to do it. Fast and practical, and it worked.
@@dbauernf he is pretty stubborn with this. I hope other people will make their research before trusting only this method. Just because something's on the internet doesn't make it legit.
Oh God this looks like a bitch to setup debating 😓 debating if I should still pick it up this looks like too much work
Just use my settings, or at least try them. If they work then you don't need to do this.
i am not going to spend all that money then i have to do all this bullshit to it
You MUST EJECT the doc on your computer before physically removing the doc from the lens. I didn't hear you explain this VERY important step prior to disconnecting the doc.
I've never done that, with anything, ever. You mean eject it in the settings?
Why buy a lens if you have to do all that not worth it
Even having to do all that, many people still believe it's the best lens out there for a crop sensor camera. It really is unique with its fixed f1.8 aperture, and the image quality for video is unmatched, especially in that price range. It does not need to be calibrated for video use, or to shoot photos in live view mode.
@@FitsandFun I think it’s a sharp lens but everyone can’t do this you figure when you spend a lot of money on something it will work correctly.. I will get the tamron 35mm 1.4
The canon 35mm 1.4 or the sigma 24mm
Those work fine
I'm not trying to sell it, makes no difference to me. But you asked why, and it's just one of those situations where you'd have to use it to understand why anyone would go through the trouble. Otherwise it wouldn't make sense to get it.
