Title: CMOS sensors with global shutter are here ... but for video only, so far
Post by: BJL on April 11, 2013, 01:45:01 pm
I have just noticed that multiple companies are offering ways to get the combination of a CMOS sensor with a global shutter (to avoid the image distortions of a rolling shutter), but all are in gear specifically for video, none in stills-only or "stills-priority" cameras. Here are the ones I know about:

Why is there nothing like this yet in any "stills-priority" camera?
One guess is that the on-sensor approaches sacrifices well capacity and thus dynamic range to make room for extra circuitry at reach photo-site, while the LCD shutters sacrifices some light or limit resolution. Also, the LCD shutters would probably still need a mechanical shutter to get shutter speeds greater than flash sync speed, where the shutter must expose the sensor progressively anyway, through a narrow "moving slit" between the curtains.
