Ah. Could be sample variation or something along those lines. Jim Kasson said pretty much the same thing about the Elmarit 28Asph on Sony A7S, but when I tried it, this is what I get wide open (click for larger):
Not perfect, but minor vignetting and color shift. Sharp wide open to the edges if focus is placed there. Biggest issue is FC, but I was pleasantly surprised how well it did after reading such awful things. Due to the size, handling and 28mm being my favorite FL, it's become my default lens. The a7S is the most forgiving Sony, but I think I'll still rent an fp at some point to test it out for myself.
Thanks for reporting back!

Can you please test the Elmarit-M 28/2.8 Asph if you have it on-hand? I've found it *more* than usable on a7S, but there is definitely FC. Most noticeable at wide apertures and up close (<3m) which is mostly how I shoot with it. The FC is the "outward" variety where center at 2m will be in focus, but then something in the extreme corners at 5m will also be in focus.
Not the case at all on film, where I have yet to detect any FC (I've looked hard) so it leads me to believe that the sensor cover glass is directly responsible. There's also some color shift, but no smearing in the corners, just sometimes that funky bokeh you get when FC is at play.
I'd love to hear that it's better on the fp?
I can't seem to get what you're getting. The center is sharp but nothing else is, the corners are REALLY soft radially out from the center it's quite bad on the FP. Also the vignetting and colour shift is worse than w/the wides I tested. In fact the FP and the 28elmarit-asph I wouldn't recommend using them together.
