What Full-Frame means in practice
A full-frame sensor at 47.3MP gives the shallowest depth of field of the three formats at any given framing and aperture, and the most sensor area to gather light with. That is the physical reason full-frame bodies tend to be the larger and heavier option: the lenses that cover the format have to be bigger too.
