- I already knew the correct calibration number for my camera body and lens before I shot the video. You will figure out the correct number through trial and error. This will take a while to figure out the number the first time.
A quick and rough tutorial on how I use live view to calibrate lenses. This is not the only way and perhaps not the best way, but it works for me. - กีฬา
I just bought a used Canon 5d mark 2 with a Tamron 24-70 f2.8 mark 1. I was wondering why it was out of focus everytime I used manual focus. This video has saved me. Much appreciated
This was a GAME CHANGER!!! I couldn't figure out why all of my portraits were turning out slightly out of focus with my Canon 85mm. Watched this video and had to adjust the lens by -17!!! Thank you so much for posting this!
After seing your video I realized how bad focus I was with my canon 50mm 1.8 and by following your instructions I was able to recalibrate my lens and now is sharp as new. And to find out how far I was I tested a couple times starting from 15 and end up at 12 of a turn.. thanks man
you did +12 or -12 ??
11 years later still great video, thank you, helped me a lot!!!!
Yeah! Such a good video!
This seems like a really simple, and FREE, way of doing this. Thanks man, i'm gonna try this out later.
Thank you so much for this very helpful video! It made me get the best out of my lens ;)
Awesome! Works the same for my 7D. Great job and thanks for the info.!
I never knew the feature was available, but only recently purchased a 5DM2. Was a Nikon user. Guess I should read the user manual cover to cover.
Anyway, thanks for the informative tutorial! I adjusted my 24-105 by +5. Made a difference.
Awesome video thank you for making this.
I calibrated it to last year when I bought the lens. I already knew it was 15 in the video. Most lenses aren't off by that much. You will just have to play with the calibration until you get what you are looking for.
great video... thanks for the help!
Good job dude! Now my 24-105 is amazing! Thanks!
I did not even know that there is such option :O Well I guess You learn Your whole life :D
Dude thank you for the tutorial, I thought my camera was not focusing well but after I found the right vale for my lens my problem disappear
Liked your easy to follow video, how far should the 5d be away from the picture on the wall ? also I have two Canon zoom lenses, 24-105 f4 and 70-200 f2.8 .Do I focus in close or midd range to calibrate both of these lenses?
Never mind. I read. Lol. Thank you sir! I've always wondered how this was done. Actually thought you needed some type of additional equipment to do this.
Wow this is so much better than all other home-made methods I've seen! Just wondering.. you had a 24-70 lens but at which lenght do you have to make your test if it's not a prime lens? For example I have a 50mm F1.4, a 70-200 F4 IS and a Tokina 16-28. It's mostly useless for wide-angle lens but for my telephoto lens should I set it at the middle of 140 or maximum 200?
Thank you man! It helped me!
you make m'y day sir, thanks.
thank you for sharing this info.
dam your the man, thanks man!!!!!!! Big respect!!!!!
Great vid!
Great video
bookmarked this video !! usefull
Hi...thanks for putting up this video. I've heard about back focus and front focus but don't know what they stand for. I know how you came up with +15....a lot of experimentation. Did you exper with both backward and frontward focus? or you went straight to backward focus. Is there one that is more prevalent than the other when it comes to adjusting focus? Thanks again!
Thanks, it helps wonders
Thank for this video!
GREAT STUFF thank YOU.
Thank you what a life saver -
I'm using the exact same body and lens as you do in this video.
Thx ! really helpful 👍
So where did you get your initial adjustment of 15? Was is basically just trial and error, or was there and indicator giving you the number?
Excellent. thank you
You don't explain where you got the value of 15 and how anyone else might be able to find it.
I thought the number would show up on the scale when I focused in live view and went back to info. My 28-135 appeared not to have any difference in focusing from AF to LV. I used a lens calibration target to do this test.
It does not meant to be 15 for all lenses, that is based of the total times you try by turning a little by little clockwise or anticlockwise until you find the best clarity for your lens. I took the number 15 as a starting point going back and fort with my lens because of the same confussion and end up in 12. That is how it works
It almost seems you have to enter a valve, then go back to shooting mode. Use auto focus again, zoom in. Check clarity, and then do this for each value and save the one that's best.
Very Constructive
Great video I have to admit, but what settings should I use? Or it doesn't matter? And what about the zoom?
Hey folks I believe he says it on his video, his lens was previously calibrated and tht is how he knew. Here's something I'm looking Ito getting after a photographer buddy of mine recommended I NOT buy the Spyder Datacolor System. The FoCal software out of UK I tried to put the link here but it did not let me. Anyways try the manual adjustment I did and it worked! It's like he said "trial and error."
thanks for the help
5d.m2 no.1. 👍
Nice video
Better way is to take different photos, and compare them in Adobe Bridge (using magnifying glass tool). I did this with my 70-200 f4 L. adjustment by -4 works best for me.
HI do we have to micro adjust every time we want to focus on something other than what we originally set focus for?
So how did you know it was 15? Do you just keep going through it and increasing the number until it is sharp?
I already knew it was 15 from previous calibrations. But it took a while to figure out it was 15. I had to keep moving it up until it was as clear as I could get it. When a lens is that off it's rough. I recomend moving it up a few clicks at a time and when you get close only move it one click at a time. It's been tack sharp since.
Welcome, thanks for watching
Great 👍
im just wondering did canon come up with any new firmwares that support micro-adjustment larger than +-20? Also my sigma 50mm 1.4 seems to work fine on 20+, but would you still suggest me to send it back to the factory? Thanks!!!
Hi, I'm clear on everthing you've done, but I don't know where you figured out it was +15. Did you just try the different numbers until it looked right? I figured the number 15 would be on the screen somewhere or it would somehow know how much I adjusted it to get the focus right. I've got a 70-300 DO lens that is soft and I'm trying to get it right. Thanks.
But where did the 15 figure get generated from ??
When Adjust by lens is highlighted, press Info for the scale. Range is +20 to -20.
thanks for the video.
However, I agree with others who say, it isn't clear how you figured out the number was 15. I'm still not sure... I'm going to go check out more videos to see if I can learn this.
when using a zoom lens where should you put the zoom to test the focus. For example on the 70mm, 120mm or 200mm?
oh so you have to go and change the meter then do the whole procedure again and again till you get the clearest focus? back and forth? yes?
Yes until it is sharpest. It is different for all lenses. The 5D Mk II will remember your settings.
So, even though this is a zoom lens, you do just one calibration at 15 and that covers all focal lengths?
can this process be done on a canon rebel t2i.
Thanks
It could be a bad lens. What lens are you using?
Is this method work after disassembly sensor and motherboard?
hello sir i want to know how u got the value 15 is it by looking the focus dial
It's from the direction the lens spins being the same when he is in live view (direction required to get max sharpness). If it changes direction you know you have gone past the best spot
Grant Kennedy We get that. But where on the screen does the camera tell us the number in the first place?
good
Hey great video! I'm at +20 and I can see that it's working, but it's still not totally sharp. Now what?
I have three zooms 16-35, 24-70 and 70-200, which focal length should I do this on? Also, I'm assuming it's also advised to do this test wide open?
Yes do it wide open. I would do it zoomed out completely. Zoom has very little to do with focus. However I would be interested to hear if the calibration is off at different zoom values.
I appreciate you reply, surprisingly on my 5D iii it has 2 different MA for both wide and tele. So that's a nice surprise i wasn't aware of.
jasonaugustmusic Thanks for the video. It is really good. But... I have FF on 70mm and it is ok on 24mm. After the calibration 70mm is ok but it is BF on 24mm. Any ideas what to do with that? Thanks in advance.
welcome
WHERE DID YOU GET 15?
It's clearly implied by the video. He kept making micro adjustments and rechecking on live-view until he arrived at 15.
People need to stop saying " What you gonna do or what you wanna do"
my question is the same. How do you figure its +15?
Oh, I am confuse... How you come up with the number 15?
Cool
Wow, I knew this lens was known for being off. I would send it to Sigma and let them recalibrate it...if it is that off.
jason
Trial and error, I knew before hand.
at 4:25 you say "lock in autofocus" but we can't see what you did to do that.
if you are using a zoom lens calibrate it on a longest focal lenght
Can this work on 7D and 6D as well?
Yes, same way... works for lens based on serial numbers so it will be lens specific... cheers
how the heck do i know what 15 is?
Why did he do it again and again. which one which? It's confusing dude!
Damn that was confusing.
Go to -20 and go from ther up to 0 ....
I already knew it was 15 from past calibrations. You will have to use trail and error to find this out.

very bad method. put picture at 45°. much easier and faster
+Mic Sku Could you elaborate?
