Got my 16-50 from Japan again, did a brick wall test, making sure the lens was absolutely parallel to the wall by putting a small whiteboard in-between the wall and lens... last time, the copy I had was very soft on the right side... this time, I think both sides are equally soft. Can guys with good copies tell me if the softness exhibited here is the "normal" softness I would expect? Or should I go after Pentax once again?
All shot at 2.8 (I also shot at f4, f5.6 and f8. Improvements are noticeable, especially at 5.6 onwards, but not perfect...)
16mm
28mm
34mm
50mm
Is it just me or is the left side a little softer tan the right?
