I've seen generalizations that full-frame sensors tend to exhibit better low-light performance and dynamic range than a cropped-sensor specifically because they tend to use larger photosites that ...
As I understand, a bigger photosite (on the sensor) enables a bigger dynamic range and also better high ISO performance. Is there a reason not to make the photosite deeper?
I have a Canon 40D and I always shoot RAW. I am overall pleased with the 40D except for its low-light performance. Anything at or above ISO 800 is unusable for my taste. Just to solve this problem I ...
