6D Markii auto-focus issues

Namra38 — Sat, 09 Dec 2017 20:34:21 GMT

Hello,

I was wondering if anyone might have any insight in an issue I have been having with a 6Dmii that I purchased at the end of August. I have been a long time Canon user and previously was using the Canon 6D as my main body (still have it). When I upgraded to the Markii I was excited for the fast frame rate and focus points. However, every lens that I use on the new body needs to be micro-adjusted, and not just by 2-3 clicks, it is requiring a negative 9-11 adjustment for each lens which I would consider excessive. All the same lenses work perfect with no adjustments needed on my old 6D body.

List of lenses:
Tamron 24-70f2.8
Tamron 70-200mm f/2.8 Di VC USD
Canon 100-400 f4.5-5.6 (Mark i)
Sigma Art 50mm f1.4

I have used online micro-adjustment tutorials to adjust each lens and am still noticing very slow speeds in AI Servo mode. My 6D has a much higher percentage of in-focus images with a subject that is moving quickly towards the camera. The Markii has been very frustrating to use, especially when I have the Marki that I have had no issues with that I can compare side by side.

Any help or suggestions would be greatly appreciated.

I have had no focus issues. There has been a firmware update, which addressed compatibility issues, not AF issues. You have a gaggle of third party lenses, whereas all of my main lenses are all Canon “L” lenses.

The camera is under warranty, so send it to Canon, and ask them to check the AFMA.

The Christmas holiday season is not the best time of the year to send gear in for repair. They have an increase in sales, and a corresponding increase in service requests. What would normally take 10-14 days to turn around will easily double that amount of time.

Plus, there is a double holiday coming up, Christmas and New Year, which is probably the worst case scenario. I once sent a camera body in during the second week of December, and did not get it back until the third week in January.

You can try a complete reset and set up from scratch. However, given your time with the 6D, you are probably in a good position to evaluate if something isn't right with the new body. Doesn't seem right that every single lens you own including Canon has to be adjusted.

With you only being 3 months into ownership, you might want to consider having the body checked by Canon to confirm nothing is wrong with the camera. If you call, I'll bet they are willing to help.

Hi -

I had the same issue. I am a long time Canon user and just purchased the 6D Mark ii at the end of November. I primarily use three lenses and all three had to be micro adjusted - one up to -14 and still wasn't focusing properly. Two of my lenses are Canons.

Canon 50mm 1.8

Canon 70-200mm 2.8

Tamron 24-70mm 2.8

I sent in it for repair and was just notified that the auto focusing mechanism was out of position. Hoping it works when it comes back!

I would definitely send it in for evaluation.

Thank you for the information! What is the process of sending something into Canon? I have never done it before

I can only confirm that I had exactly the same issues with AF and my newly purchased 6D mark II.

The lenses I used with this body:

Tamron 70-200mm f/2.8 SP Di VC USD
Canon EF 50mm f/1.4
Canon EF 24mm f/1.4 L

Canon EF 35mm f/2 IS USM

AF was almost always out of the focus. I have given up and returned it becasue didn't want to go through warranty process.

Interestingly AF in live View mode worked flawlessly.

In the US, call 1-800-OK-CANON. There is also a web site link that you can use, too, to set up a return authorization ticket.

Call Canon and tell them you want to send it in for a repair issue and it is still under warranty. They will provide you with paperwork to include with it and you must also provide a copy of your receipt of purchase to prove it is under warranty still, which they didn't bother to tell me the first time and they wanted to charge me for repair.

When I receive my camera back, I will let you know if the issue is corrected.

I'm curious to know AnnaMaria if you purchased another 6D Mark ii after returning the defective one? And if so, was it okay. I'm really concerned that I'm going to get my camera back and it will stil have an issue. Kinda wishing I had just returned it now...

I'm getting 5D Mark IV. Waiting for delivery.

Hello,

Have you tried turning-off the lens aberration correction in Shoot menu #1? [ ...turn all the available settings in the sub-menu to off ]

This feature is specifically for use with Canon lenses, to correct JPEGs 'in camera' and RAW images when processed in Canon's Digital Photo Professional software.

It's been reported that it can be problematic on the 6D mkii (and other recent Canons, incl. the original 6D) for third-party lenses from Tamron and Sigma. See these links:

I ended up sending mine in to get serviced, I heard back yesterday that there was an issue with the focusing mechanism:
The Canon Factory Service Center found that the imaging sensor assembly was out of position causing the focus to operate improperly. The flange was adjusted and an auto focus adjustment was performed. Camera functions were also confirmed.

I will hopefully be getting it back tomorrow.

My 6D Mark ii wasn't consistently focusing with any of my lenses - 2 canon and 1 tamron. I sent it to Canon, the auto-focus mechanism was "out of position" they said. I received it back and it was better; however, it still was never sharp where my focal point was. Kept trying lens adjustments for back/front focus and I just gave up. I'm not spending that much $ and not be able to shoot confidently. I returned the camera. I am considering ordering another and give the body one more try.

I have also communicated with Tamron because it didn't play friendly (the most) with that lens. There solution is as you stated or to also send it in for a firmware update. If I get a new one, I'll see if it does the same with the Tamron.

Thanks for the info -

That was the same with mine. I still wasn't please when I got it back and have returned it. I hope it works out for you!!

Hi,

I have a 6D mk2 that I purchased in November and only have Canon lens. I seem to have bad auto focus and the depth of field is very small even at f19.

Namra38 — Sat, 03 Feb 2018 23:50:09 GMT

I got mine back and have only done some initial tests but it does not appear like the issue has been fixed at all, going to have to micro adjust my lenses again. Pretty dissapointing.

I don't realize that a camera can be returned after sending in for repair. Learn something everyday.

Shoot, I purchased a 6dMarkII the end of November and struggled with this exact problem. I returned the camera to B&H and got a new one, but am still unhappy with the inconsistent forward focusing I'm experiencing. I think I'm outside of my return period and am tempted to try and have it repaired. Did it cost you anything?

Thanks

If it is within the year warranty it is a free repair you just have to pay shipping to get it to the service center which ended up costing me about $50 after insuring the package for the full value of the camera.
