Hi! Later this year I'm moving to a strange and distant land for an indeterminate amount of time, and I want to document my experiences there. My current crappy, dying camera is NOT up to the task. Here's what I am looking for (Note: I honestly don't have enough experience to know if what I'm asking for is reasonable or not, so let me know if I'm being stupid): -700 USD or less -Obviously, good image quality -Versatile enough to photograph anything and everything (close people, far people, landscapes, monuments, signs, night, day) decently, with ONE lens if possible. This is the most important consideration, because I plan to keep this camera in my bag and on my person 24 hours a day. Am I asking the impossible? I'm too ignorant of photography to know. -Since I will be carrying this camera everywhere, not being bulky and heavy would be a huge plus. I'd rather have a nice, compact point-and-shoot, but I've heard DSLRs are more versatile because of the better depth of field range and ISOs (and obviously the interchangeable parts), but lugging around a big heavy camera isn't really what I want to do if I can avoid it. Any advice or suggestions would be appreciated. Thanks!
