I havent really thought about this questionindepth, but the question popped into my head on the way home from doing senior pictures yesterday. Is there a need for a "shutter" in a digital camera? If I understand it correctly (which I probly dont) the sensor is on for the duration of the exposure. So lets say you had a exposure of 1/125 if the sensor is on for 1/125 is there a need for a shutter staying open for the same duration? If there wasnt sync speeds could essentially go as high as well....Im not really sure because there wouldnt be a mechanical shutter having to move.


Let me know what you think, Im no expert just something I was thinking about last evening.


Thanks
