I am an artist who uses an older Canon S50 for shooting my paintings. The LCD screen is really useful for this purpose. Since the screen doesn?t swivel, I rigged a tiny mirror attached to it so I can shoot hand-held with the art flat on the ground and the camera held up high, horizontally. I am looking to upgrade to a better camera. I want a higher megapixel, and BIGGER CHIP (to reduce the terrible barrel distortion I get). I thought about a DSLR, but without LIVE PREVIEW, it is useless to photograph artwork. Any recommendations? Do any higher-end point-and-shoots have a large enough chip that would reduce barrel distortion? Any DSLRs with live preview? Thanks!
