6D Markii auto-focus issues

[Namra38]

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'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...

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:

Hope this helps!

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.

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.
