Re: Kitlens of Nex-F3 looks decentered and blurry corners

I will try a flat sucject test with tripod today to make sure. I also don't know the field curvature with this lens. I doubt it is straight.
In the very centre (the few shots I tried with it so far) the sigma 30mm and the kitliens at 30mm are both very equal. but at midframe or border the sigma is better for sure.

Alas, it's impossible to say. At f/4 it's unlikely that both the background trees and the foreground dirt -- the things in the corners -- are both in focus. In fact neither of them may be in focus since the plane of focus appears to intersect the gazebo-like structure in the middle of the frame.| Post (hide subjects) | Posted by | When | |
