I'm going travelling in a few months, and need a new camera to take with me. Since I'll be doing a lot of backpacking and moving around I'm mostly looking for a camera that is compact in size, but can also take decent pictures. I don't expect it to be able to take professional looking pictures or anything, just something that isn't too much of a PITA to carry around with me all the time and optical zoom is a must (not a fan of digital zoom at all). Water resistant would be nice, but not a requirement. I'd be willing to spend upwards of $500ish on this camera, but would rather spend less (who wouldnt?). Any suggestions are welcome to this extreme camera n00b.
