I hope I am posting this in the correct section.
My question is: why do dSLR cameras use mechanical shutters?
Wouldn't it be easier and cheaper to have a sensor that can turn itself off to finish the exposure, instead of using a shutter? If my knowledge is correct, video cameras don't use shutters, so why must dSLRs?
It seems like the shutter is one of the more problematic elements in dSLRs since they break quickly. Why have them at all?
