I'm sort of randomly looking for a new digital camera. I'm looking for an ability to control various aspects of the exposure (if you can call it that). I'm looking for control over depth of field and shutter speed, but want something fairly small. I think something along the lines of 4Mpixels will get the job done and should keep me from outgrowing it.

I know fish has a nifty Canon that does all that stuff, but I'm curious about whether other folks have any other suggestions. If there's one thing that makes riding fun, it's taking a whole pile of pictures and then sharing them.
