hmm, nice idea Godfrey, pity though having to crop off the sides off such an amazing sensor, and glass.A clever dodge around all the M-mount lens corner smearing occurred to me this morning. I love to shoot square format (old Rolleiflex/Hasselblad user).
So just crop what the A7 nets to a central square ... that's still a 16Mpixel image or 24Mpixel with the A7r. Aside from broad-based color shifting, all the corner problems will be gone. That opens up using a much larger range of M-mount lenses for me.
Woo hoo! Back to squares!
(I'm testing the M-Rokkor 40/2 on the A7 today. So far, I'm finding it a better fit ergonomically than the Nokton 40/1.4, and I think it will produce a sweeter photograph too.)

If one is going to crop, is it more advantageous using leica M on A7/r or maybe just use leica m on a Ricoh GXR A12?
