A6500 issue with focus when using the viewfinder

[Rockline]

hi all, I've got an A6500 with a Sigma lens (30mm 1.4 DC-DN).

When I take a picture of a landscape (all green squares appear when focusing) it works nicely. However, if I take the same picture (with again all green squares when focusing) but this time looking through the ViewFinder (rather than looking at the screen) then the output picture isn't sharp anymore.

Any idea? (I have the latest firmwares installed)

But are you using eye start af?

If yes, why?

If no, why you mentioned it?

Anyway it sounds strange to me the issue you claim.

Are you sure that you don’t move af rotor on lens?
