Autofocus problems 7D II cause frustration (poor with fast lenses, artificial light)
3

Hi,

I just bought a 7 D II to replace my old backup crop Canon (was a 50d). I have to say I kind of seem to have been mislead by agressive marketing.

The camera has some serious issues with fast lenses. Both a Canon EF 100mm / 2 and a Canon EF 85mm / 1.2 are misfocussing when used wide open way too many times. Using single shot.

Tried to eliminate my errors on a tripod and under bright (if grey) daylight and it does persist.

The 50D focuses perfectly with the same lenses.

Slower lenses, such as the 2.8 zooms are no issue, but it is unreliable with fast lenses. And all my favorite lenses are fast.

Now I wonder if I have bought the dark brother to the notorious ill-focussing 70D variants, which I avoided just because of this.

Then yesterday night I shot some dancing action (obviously poor light) and the keeper rate was abysmal with servo AF, using 70-200/2.8.

This morning me and my neighbor who bought his 7 D II even earlier than myself shot his dogs with the 70-200 and both worked fine. So we then assumed there might be the old issue with reddish artificial light and - yep, the camera seems to get unreliable when confronted with a certain orange light.

While I find many features nice in this camera, an unreliable autofocus system sucks big time. I bought it exactly for it's AF system, which now fails on me.

I think I will ask for a replacement camera, since I certainly do not want to spend any more time testing a product with obvious quality control issues. I do hope, the second item will be better and I can just take pictures.

Does anyone here have similar issues ?

Similar "issue" -- all of my lenses seemed to "just work" on the 70D, so I never even investigated the micro-focus adjustment feature.

It sure FEELS like my pictures now with the 7D Mark II simply aren't focused as well.

I'm annoyed that I apparently have to MFA all my lenses, but right now I'm expecting MFA to fix everything.

Mine focuses perfectly with my 35 F2 IS and 85 F1.8. Haven't had a chance yet to test tracking.

Ya that can be a real annoyance. Alternatively you could pack up all your lenses and bodies and send it in to Canon Service to be aligned. Then you won't be annoyed with having to MFA but will be without gear for a seemingly infinitely long time. Another alternative would be to return this 7D II copy for another.  My experience with the 7D was that no two bodies will have the same amount of MFA with the same lens. You might get lucky.

What are you saying? He's not allowed to report his problem on this gear forum specific to the model he has acquired? That you are in denial of the problem that some experienced in 2009?

You had trouble with a 70D also?  With the same lenses?

In camera adjustment seems a poor workaround for the artificial light issues. I can adjust the lenses to work better, but then they are off under daylight. I guess you understand that it's not my target to adjust MFA every day and night.

The 7D2 issues with my fast lenses are not possible to cover by using MFA in camera. It seems random to a degree.

No I never owned a 70D, just because I read of so many users who had issues with fast lenses and was scared to run into this as I hate these testing things. My equipment dealer actually was aware of the problem as well. And as far as I can gather it is still unresolved there.

I didn't mean to suggest that MFA and iTR would necessarily fix the problem. I was asking whether you were using those things. I would be interested to know whether, and how, iTR affects your issue in artificial light. If your problem with fast lenses seems random, then MFA clearly won't fix it. If, after some more controlled testing, your problems remain, you should probably just exchange the camera. I haven't seen other reports of these specific problems with the 7DII, so, with any luck, it's a random defect, and you'll get a properly working one in exchange.

You can get a bad copy of anything.  Start by exchanging your 7D2.

The vast majority of 70D owners have been tickled pink.  My own has a nearly 100% hit rate on static subjects (with my fast lenses).  And much better consistency than my 50D with moving subjects (about double the keeper percentage).

Re: Autofocus problems 7D II cause frustration (poor with fast lenses, artificial light)

I just got my 7D II yesterday, so I only had a few hours to play with it before the sun set, however, I was seeing some major focusing issues with my EFS 17-85 lens.  My previous camera was an old 450D, and that lens never had focusing issues before.  With the 7D II in certain lighting conditions it simply cannot focus whatsoever.  The servo goes crazy and the lens barrel is spinning all over the place trying to find focus.  Doesn't matter what I point it at - high contrast or low contrast does the same thing.  But it was only in that outdoor lighting about 10 minutes before sunset.  Still plenty of light, but not exactly bright outside.  The camera would not focus on anything to save its life!  But back inside where it was even darker it seemed to be working fine.  Very odd.  Going to play with it more today when it gets lighter out.

One of the 7D2 claims to fame is low light focusing.

Does anyone here have similar issues ?

I had a similar problem last Friday night while shooting football with my 300mm 2.8 is II. I chalked that night up to a possible settings issue so I checked them all over the week end and shot again on Monday night (same field and lighting) the issue did not get any better and those images that did hit the focus where very soft.

I do not see the need for a camera that shoots 10 frame a second if only 2 are usable, my 5DIII gets almost every shot and the ones it misses are the photographers problem not the camera.

Anyway the 7DII is out for delivery to CPS this morning, hopefully they can correct this issue or it will be on it's way back to the vendor.

I'm finding that I tend to gravitate back to the 70D, as I just don't trust my 7D Mark II to focus with my lenses...

Servo AF is for subjects which are changing focus distance from the camera and must be tracked. Moving subjects standing in pretty much the same place (IF that is the case here) are probably not suitable for servo AF. When you select servo you tell the camera 'find the part of the image that is changing focus distance' and where there is nothing that really is doing that, you've sent the AF off on a wild goose chase.

Saw a video from Canon once describing servo AF in just that way, and I am wondering if maybe you need to leave the servo AF off unless you are shooting subjects which are really changing focus distance significantly.

Hope you don't mind the comment but I seriously doubt Canon has released this camera after so much testing and so much AF experience with an 'unreliable' AF system, and I have seen many instances of people using AF in servo mode when it's not the best choice of setting. In fact I learned a long time ago that there are a rather narrow range of circumstances when it's the right choice, far fewer than I would have assumed.
