TY sir, This lens is fun to use
note the blueish tinge on the tin roof--CA? The funny thing is the lens will not purple fringe, even wide open again bright lights, yet sometimes bright reflections are blued. You can also see what appears to be spherical aberation in the lower corners, however the edges up higher are quite good. It's possible to get quite a sharp corner, but you have to focus for it.
below: f4
It's pretty sharp, even wide open, but the serious resolution begins at 5.6 where all but the extreme corners are pretty impressive really.
f/2.8 sharpness test: centers seem quite respectable
100
It will be very interesting to see this lens on the Nex-7, where the sensors will be optimised for corner performance, and conrnerfix is no longer needed for the wide CVs.
It's no ZM 25/2.8, but then again I didn't pay a grand AND it's 100 grams lighter

Frankly, without any peeping and ignoring the far corners, it produces images which look fine next to my leica 50/2 v4.
here is a 100 from near center of the first image, which is at least f/8
I do have a fantasic 24, the nFD 24/2, which many consider the best FD lens ever made, and while it's not at all large, it's big enough that I don't all always have it with me--but this one BEGS to be used
🙂
