Many thanks Karl. That's exactly what I've been doing this week with some of my older but most liked lenses and everyone else simply makes it so extremely complicated and at the end tries to sell you some sort of tool of which I now have a collection of and enough to open my own online store. Thanks again.

3 years old, and still extremely helpful today. Thank you for this key information at virtually no cost. 👍👍

Hello!! I am VERY glad to see you do a complete video on this, as I have been getting contradictory information on the importance of this procedure for each lens that you have a focus issue with, isolating the possibility of camera damage! If a level of photographer such as yourself does not consider it rubbish, then I feel much better continuing to eschew the importance of knowing - and performing - this procedure to my “followers” who question best practices for obtaining the highest quality images they can obtain with their equipment. Take care, and I am looking forward to devouring all that you and your team is making available on your education site! BLAYZE! USA!

Thank you Karl this was really use full, I'll have to do this on one of my lenses I've had a bit of hit and misses with when it comes to auto focus.

Thats sooo Useful tip, I have struggled with the same problem for a very long time and didn't know what the problem was. Thank you Guru Taylor !!

Super timing! I've been lately suffering from misfocus on some lenses. Great, thanks!

I have tried these methods with other printouts, I will try your method today, I have a few lenses to get thru. hope it works.Thanks, great tutorial

On such small differences in focus, the thickness of the rulers starts to matter, though. Thick rulers bring farther numbers a little bit back into focus, so, your results may be off again minutely. Not hugely, but enough that it can matter again. That's why a printed ruler that's necessarily at the same height as the focused line is that little edge better than physical rulers.

I've needed to do this for a while now and this is a perfectly simple explanation. Thanks!

Brilliant video and super helpful. It's all these little things that make a big difference. Thanks Karl

Thanks a lot Karl, I have done this before but your method is super easy, super handy. God bless you.

Very helpful video. Neat, simple and absolutely practical! Thanks Karl for sharing your knowledge with us.🙏

So useful. This video is perfect. Time to check all my lenses. Thank you for posting.

Love this super east way of doing the AF Tune. I just got a new 85 this afternoon... it was out by -18 right outta the box!! WOOF! Thanks for amazing content as always Sir! - J

Thank you for the information and for taking the time to make a video to share it!

Explained very well. Let me share this with my list tonight.

Thank you very much Karl, I always appreciate your expertise. 👍🏻👍🏻👍🏻

So helpful wonderful video and so well presented straight to the point. Thanks so much for uploading.

WOW! Probably one of the BEST educational photography clips I'd seen on KZread since I'd been a photographer! Excellent video!

Thank you, you have explained very well, how simply and inexpensively this process can be done! This tutorial has helped me to simply calibrate a rear focused lens on my camera. Cheers!

I had no idea it was this simple. Thanks for sharing!

Another brilliant video Karl. Thanks for sharing mate.

Very clear tutorial , thank you Karl!

This is literally the best video I’ve ever seen on the subject. Thank you so much because I could not figure out why my pictures are not coming out sharp with my new camera.

Make sure select calibrate 'by lense' and not 'by distance'. otherwise the other lenses will become out of focus I suspect.

Thank you for this tutorial, immensely useful!

Excellent and clear explanation on how to do this, thanks.

It’s important to reinforce the need to assure your board and rulers are flat. Any bowing or curvature will impact your results.

put a piece of glass on the table, and work on the glass, thats 99.999% flat made, "flatter" then most tables at least

This is very nice and simple. I have noticed my ef 50 1.8 on my rp tends to back focus a little bit. I need to acquire a tripod and use this method to calibrate. Good, simple video.

How far away was your camera to the target? I have same lens and extender and need to adjust it. thanks.

Súper useful, thank you!

Thank you so much Karl, this was very useful, so that I could avoid investing into an AF calibration tool, not to mention returning lenses along with a dispute procedure. The calibration tools I have seen always had the ruler stricktly set to a 45 degree angle relative to the plain of focus. In your tutorial there was little attention paid to that angle; does that setting play a critical role at all?

This the literally the best!! Thanks!!

To calibrate our AF lenses in lab we use Reikan software wich is really good even with zoom lenses and semi automatic. The soft gives also a correction chart at the end of the process.

Thank you this is awsome

Interesting thanks for the tip

Very helpful and simply put video. Thanks for the info, hope it works for me!

Useful, thankyou.

Just did this with mew new Canon 500mm F4 Mark I. I had made a white board out of 4 pieces of A3 taped together and place my camera and tripod quite far on the floor in the distance. Focused on the line, then Manual focused to make sure it was not in focus, switched back to AF focused on the line, took a snap. then placed the rulers took a snap, both sides 10cm was pin sharp and 8 was blurry, 9 was sharper and same on 11 and 12. Fantastic guide. Subscribed!

Great video! Much thanks, that is so useful! Do you happen to have a video on how to detect decentered lenses? Just asking, since I seem to have a 85mm lens that's sharp on the bottom and fuzzy on the top...

Well I never knew that, thanks Karl.

Thank you for your nice video! Why you didnt use LCDfor outofocus? Is is because LCD is based on contrast detect AF?

Wow. So educative

Great video. So... once it focuses on the line, do you change it back to manual to lock it, or do you let the autofoucs try to focus the line between the rulers after you adjust the number?

thanks for the tips! one question: will this technique (with the exception of using the in-camera focus adjustment) work basically the same for calibrating my Tamron 150-600 lens, using my Tap-in console?

Thanks my guy

Yes, verry helpfull this video. I just subscribed.

Thank you for the tutorial I have a question im sure its dumb but let's say I have 3 lenses and I collaborate each will my camera just rember this? I have a 5dmarkiii im new to full frame and I've bever collaborated before.

How often should we calibrate? I've heard also that when driving and the lens is packed away and shaking in the vehicle, that can throw out the focus also

Also it will help if one uses some masking tape to secure the white board to prevent movement.

i do this these tests with a remote to reduce movement

I went on a shoot today in beautiful cloudless sky in the Bavarian Alps and want to test my Sigma ART DG/DN 35mm f1.4 I bought it in Spring 2023 but hadn't used it much and then I had a big bike crash where my well padded camera bag containing my Sony A7 iii took a knock and I hadnt used it since then. To say I was disappointed with today's results is an understatement so I went looking in YT for help and BINGO we found each other. I found " AF Micro-Adjustments" in the gruesome Sony Menus so tomorrow is the day

Sorry to hear about your camera gear I hope it isn't actually damaged.

Great idea, just wanted to ask what lens did you use for this video?
