What Canon models do have support for smaller RAW (sRAW, mRAW) sizes?
Seems the EOS 60D does, but the 600D and 650D doesn't ... is there a list? Is this not a standard feature?
This is a feature of all 2-digit models and 1-digit models since about 2007.
This is a Canon only feature. I do not know of anyone who uses it honestly since those who shoot RAW do it to get all sensor information.
