That stinks. I've had excellent luck with my 5D3, and I shoot tons of action stuff. It's almost magical on focus, similar to the reports I've heard about the 1DX.

yeah, not sure. In those cases maybe was user error as I said. But I'm quite positive I'm doing things right on the Mark II. If I can make it home before it's dark, I'll do more tests and see how it goes.

One thing I found very nice about the 7D2 versus the 5D3 is the ability to put two different focus "cases" on the two different back buttons. One for BIF in the sky and one for BIF below the tree tops :cool: I'd love to see that in a 5D3 firmware update.

All I can suggest is for all of you with AF issues to start a dedicated "Does Your XYZ have Focusing Issues", like the 70D, 1D3, etc. This way there can be a consolidated set of responses that allow you to isolate the issue down. Doing it here where there is a wide range of things being discussed isn't very organized and won't provide any real value.

It appears as though some are having problems with inconsistent focus. It is back focusing one time them front focusing the next.

I have owned all the xxD lines from the 20D to the current 7D2. Also all the 3 - 5D's. The only camera I have ever sent to Canon for a focus tune up was my 7Dc which I thought was front and back focusing erratically. When it came back it was bang on.

I'm still on the fence with my 7D2. I still have to do a couple of live view shots and then do a series of shots in phase detection to compare.

I only had birds at the feeders at my cottage over the weekend so I did not have a chance at BIF. It seems to me by looking at the branch at the bottom it is front focusing. The focus point was on the eye but it is hard to tell with the angle. I randomly tried MFA 5 to 10 ticks to compensate and at times it looked better at 10 and at some times worse. If MFA needs more than 3 to 4 ticks than as far as I'm concerned it is Canon's responsibility, not mine. I don't care if it goes to 20. I can produce lots of sharp images that have no MFA with multiple bodies. I never use it. I realize the camera can be at one end of the spec and the lens at the other. I have found factory calibrated gear, even if the camera and lens where done in separate departments yields excellent results.

I'm still going to go with the issue is my technique but I will be doing more testing to see.

Yeah, agreed. I know the AF is complex. But as he said, if it can't focus properly/consistently in One Shot with, with center AF on a static target, somethings very wrong. :(

Then again. I've tried 2 different 5D III's, rented and a buddies. Testing with like 5 different lenses. In both cases, I had a very hard time getting any sharp images. Most were outta focus. But those were mostly all action shots, so could definitely have been user error or something else in those cases.

However, ANOTHER guy I know, who uses a Mark III, said the AF is inconsistent and he has issues with it on his 500 F/4 sometimes.

Again, it depends on what is on that center point. The AF sensors seems to overlap and may not quite align with the boxes on the LCD screen. That seems to be more of a representation of where the AF sensor might be, but in reality, they could be slightly off. So if you put your target on a boundary of an AF point, you could be confusing that AF point or not getting the info to it that it needs to focus.

Things that affect AF:
- AF settings
- AF point placement vs LCD overlay
- Subject material
- Lens
- AFMA
- Lighting (type and amount)
- AF mode
- <other things I cannot think of>

Do you have a 7D2?

Have you ever had a Canon body in the past where the AF points are all packed in there unlike the 9pt systems? Just as on the 7D, the AF point is larger than the boxes on the screen, and you have to find the right mode. Sometimes spot AF is the answer, sometimes its single point with expansion. I don't know your history, but people have had these issues with others, and it only makes sense to state the same points made before, however obvious they might be.

Yes, I've got the 70D (which has a number of "packed" AF points, and I can consistently make sharp images with it (not all , but at least most, are).

No, but I have been down this road many a time with different models, and know all there is to know, minus a few things, about the 7D2 predecessor, and these exact same threads came up, as they did on the 70D, etc. ;)

And as happened in the similar 70D thread, many people who don't even own the body will come in and just drop all sorts of non-sensical denials of there being a problem to begin with?

Not everyone could, both with the 7D and 70D. Now with the 7D2, the spread is even more dense. :)

stunning image!

I'd be pissed if I shot something like that had only a jpg to show for it.

Sure that will happen, but you still need a single dedicated thread where people can start to list their settings, their scenes, etc. Especially if you want to get to the bottom of the issue, if there is one. If people get into that thread and derail it, simply report the posts and the mods will take care of the rest.

You know all there is to know? Seriously?

The title of the thread is "7D2 owners unite! Discuss and post photos". 7D2 owners.

Well of course, except for the "minus a few things" that I also had in my comment that you missed, and it does appear I was the keeper of all things 7D back in the day. :D

And thus why I suggest a dedicated AF issue thread, so you can carry on your discussions from this thread and into something more constructive and concrete. I want to see more pictures. Hopefully more from indoor sports, or night time outdoor sports!
