I took a few pictures with this Paxette lens on my a7. A beautiful tiny lens. But the edges are soft to a point that makes me suspect a flipped lens element.

In my memory, this lens is soft WO at my NEX-5N. Stop down to F5.6 is much better but I expect it will be a different story on A7.

Yes I'm obviously not expecting planar performance here. But I expected it to be as good as the Cassar S 2.8/50.

Indeed stopping down helped a lot on the a7 too.

I have no idea. May be my copy is faulty or it is really not a sharp lens.

I took these night photos with the same lens.

f/16 i think. Good sharpness at this setting.

Here are two photos taken with 5N. The first is F2.8 and the second is F4.

You are welcomed.

By the way, the bokeh is pretty good to me....

Yes nice triplet bokeh.
