To be honest: i see lots of CA and very little sharpness.....
There are plenty 28mm lenses out there that are WAY better! |
It's not just the lens, I think a big part of the problem is the OP is using it on a Pentax with its insane crop factor. Effectively it's magnifying a really tiny part of the image circle to absurd proportions, thereby making the lens look very soft and at the same time making aberations look several times larger than they would be on a full frame sensor or even just on aps-c or m4/3. No much sense using a Pentax for adapting FF glass in my opinion.
P.S.: Also just my opinion, but the processing on a few of these shots is horrendous. |
