>>4361433Have you fine tuned focus?
Not sure about that camera but my Nikon has auto focus fine tune, zooms can be off at one end so a little hard to fine tune.
Basically focus on 15cm line on a ruler a few meters away, see if the centre of focus is exactly at 15cm or if 14 or 16 is more in focus etc.
if it’s off you can add + or - fine tune until it’s bang on.
