Here is the pen wide story. Now this is on the nex-5, but the issue is so extreme I can\'t believe it would resolve on the 5n.

Pen-f 20/3.5: nice centers, edges, let alone corners soft to the point of fuzziness.

Pen 25/2.8: Phenomenal Centers: I don\'t think I have a lens sharper in the center than this, including my nikkor 55/3.5 diamond grip. But the sides, let alone corners are very fuzzy.
I suspect its SA from the lens design pure and simple. I say this because it is possible to focus the corners---I should have do this during these test shots today, but did not think of it.
But later I shot this jeep with the new 20 wide open
next to it is a red truck with chrome rail on the bed runs to the edge: it is sharp all the way to the edge! Looking a bit more at other samples the 20 is actually quite impressive: you just have to be picky with what you are shooting and take the SA into account.
