Top crop is using the left sensor. It doesn't matter what the subject is. The focus error is 100% repeatable. If your camera does not do this then I very glad, Robin.

Thanks. It doesn't do that unless the lens is poor in that area of the field.

I agree, nothing is in focus on the top crop, so it's not a back or front focus issue, likely just a resolution problem of lens. This is not "minor" regarding focus, and it doesn't look like a focus problem.

Sorry, guys. The camera does this on ANY lens using the left point. It is most noticeable with fast glass. There is no in-focus elements visible in the left-point shot because it's a crop of the OOF area and not the whole image.

Really, that should be obvious.

Robert

No, it's not obvious. If AF point is in that area, small AF variations should make points either behind or in front in focus. It's just blurred, and could have other cause, like a lens lack of resolution there. Can you please post a larger crop of that file?
