that isn't retro-focus, since the sensors are expecting all light to be
coming in perpendicularly, not from a optic node very close to the center of
the lens. THAT could be handled by a firmware mod, to give appropriately
more exposure towards the edges.
CORRECTION: The A7R actually addresses that! Not in software, but with
lenses on the sensor chip!
