I've just upgraded from a cropped sensor a6500 to an A7riii and I'm finding some of my photos soft for no apparent reason. The shot below was taken with a Tamron 28-200 at 35mm, 1/200, f8 so should (imho) be pin sharp. I'm assuming I would have focused on the group of people but not one part of this image is bang in focus.

I'm getting lots of good, sharp pics but some like this so I don't think it's a lens calibration issue.Could it be motion blur even at 1/200 on a wide shot like this or am I doing something wrong in the camera setup maybe?

Thanks in advance for your help.

Thanks. in advance.

I’d consider atmospheric issues. Looks like a sunny day with a beach absorbing a nd then radiating heat. Shots taken at a distance. Good recipe for jello type fuzziness.
