I have a Pentax K-1m2 and the DFA 28-105. I noticed recently that my pictures are looking soft. So I did a test and found out that at different focal length the fine adjust is different.

-at 28mm its +4

_at 50mm its -4

-at 105 mm its -5

Is this pretty normal for this lens or is this just happening over times.

How do you people deal with that?

Thank you for any input.


How many times are you testing the lens at each FL to come up with your +4 at 28mm for example ?
