Yes, exactly!
If you take a look at page 1 of this thread, I already posted some images in standard web size and 100% crops from the corners.

Does it matter where the plane of focus is/was? I am not sure if pixel peeping needs to be in focus plane or does not matter. Mostly because i do not exactly understand pixel peeping. I realize sharp image from out of focus, obviously pixels has something to do with image quality, not sure I understand about corner pixel peeping.

I don't know how you set your focus point...

If you can track that using a software, it would be obviously helpful.

But if you used a relatively small aperture and the focus point is somewhere on the subject, it shouldn't be a problem to assess the image quality in any case.

In underwater wide-angle photography, the edges of the image, and especially the corners, are always problematic in terms of sharpness due to the laws of physics. Therefore, it is a constant struggle for underwater photographers to assemble a camera system that overcomes these physical limitations.😁
