The red square means the focus point was active at the time of capture, black square means it wasn't. Eg, if you are using AF-On to enable focus but let it go the AF isn't active when the image was captured (and all you'd need to to is sway a little on your feet forward or backwards to through the focal plane off the subject).

Since there's only one point showing in your image above, I'd hazard a guess that these images were captured in live view with a single point selected and you have AF removed from the shutter.

Thanks!

I've been sweating these results and have learned a bit in the last few hours. I think I've solved it now - might be trivial for many, I guess.

Yes, I was using back-button focus. I let go of the button after getting focus. No need to keep focusing once it's focused, is there? But somehow the focus must have shifted, on every single shot taken that way, and those shots are all soft. For the last few, I must have kept my thumb on the AF-ON button while clicking and got good focus in those.

Phew, so it's not the 7D2 or the lens. Nor was it hand-holding a long focal length, nor the vibration of the car I was in.

This was the first time using BBF for me, and a good lesson on how to do it right.

Glad to help and you figured it out - also glad I'm not the only one who seems to unconsciously move forward or backward when I think I'm standing or sitting still! I have to be really careful on the occasions I shoot one-shot or let go of AF-On, especially when shooting with a shallow DOF.

Looks like there could be a change in the behaviour to in the AF point display between DPP 3 & 4 - I've uninstalled version 3 so can't test that any more.

All the OOF shots were taken from my car, so little chance of swaying out of focus. Instead I must have disturbed the focus ring somehow for each shot.

At the end of this sequence I got out of the car, risking spooking the bird. This had two unexpected benefits: I inadvertantly kept the AF button pressed while shooting, plus it got the bird's attention, which then turned its head towards me and opened its beautiful yellow eyes wide.

I'm having some issues getting consistent focus on this snowy owl. Took more than 50 shots ... happy that half a dozen were sharp, but the others were blurry. That's scary, so I'm doing checking to see if I can figure out what went wrong.

As part of that, I'm displaying AF points in DPP, and I noticed sometimes the AF squares are depicted black, and sometimes red. Does anyone know the significance? I would really like to know, because for these shots, only the shots with red AF points gave sharp results.

I can't seem to find a manual for DPP 4, and the DPP 3 manual doesn't talk about AF points.

I think red indicates the focus point was locked and black just shows the selected but unlocked focus point, but I am not 100% sure.

Sending number 2 back.

Anyone have success with one ordered recently from Adorama or BH? May try #3 before I give up.

Yes the red shows which AF point/s locked. If you focus and recompose in one shot it will not show the actual AF point you locked on. Only were it wound up after recomposing. In AI Servo if you are shooting and the point goes off a bird for instance it may show the AF point locked in the sky. This can also vary in the bird itself you were tracking on the head and the point shows at the tail. So you have to pay attention to that.

IN DPP 4. First off you can select if you want AF points to be visible in the thumbnails. Top bar. Thumbnails - AF Points. I found this irritating so I unchecked it. In Tools - AF Display Settings you select to view all AF points and it will show locked focus points in red. Or you can choose Show Only AF points in focus which I prefer. Easier to look at ones in focus than all 65 AF points.

You can also set your cam so the AF point/s are displayed on the LCD.

Thanks!

Still doesn't give much info about the AF points. (It's OK, red means focus locked.)

Mine came from Adorama last week. Had them pull me one from another shipment. Nowhere near as bad as the first, but also nowhere near my 1D4. It ships back tomorrow.

Would love to get your take on my recent experiences:

I've purchased all 3 7D2 bodies from Adorama...2 have gone back and one may still ;)

I think it's just luck of the draw. Adorama customer support is awesome, and I'd definitely order from them again.

That seems about right.

I haven't used the 5D enough to compare exactly.
Although I had really bad AF/AF experience with the 5D III when I rented it, at least for action. Pretty much everyshot was very outta focus on anything moving. But that could have been user error. I had sharp images on still subjects from what I remember.


But my 7D II''s give random results with still and moving subjects, in any/every way I've tried.
