Any of the Canon G-series
is supposed to have the same *sized* sensor as the crop-sensor DSLRs.
The camera I've been coveting for this project is the Sigma DP2s (*
http://tinyurl.com/Sigma-DP2s*). The sigma has a built in intervalometer
function in the stock firmware, and has a super awesome sensor that is
supposed to work well in low-light situations (
Unfortunately the future of my employment status leaves me a bit
trepidatious to spend much money on a new camera.
