MedF has an advantage over 35: well capacity of the CCD. You can put
just as many pixels (or even more) but they are *bigger*. As you
probably don't want to cart liquid N2 or an peltier cooler and fridge
with you, the read out noise plus dark current is stuck at 20-30
electrons/sec. Simular for the CMOS one. So to get the brightness
range you need a *HUGE* well capacity. This is why the scanning
MedF backs still hold their market. A MedF lens is a good match
for CCDs, as on top line 35 lenses you must reduce the resolution
to prevent aliasing. MedF lenses are about right for 2 pixels
per line, the limit. But larger one with a higher capacity.
BTW, I'd not be supprised if Canon had a 1200 odd DO in the
pipeline. And possible a 2000 or more at last.
