The one I pack around is a pocket-sized Sony Cyber-shot Exmor R AVCHD.  It serves my purposes, and has video capabilities.  Now if I'd just read the book to figure out what all it can do. :?

I think you should ask R A what kind of camera he uses.  His photos are so very clear with remarkable contrast.  That would be a better camera to use, but it might be a bit bigger and more cumbersome than the one I carry.
