The main problem with the K-5 (right) is size (although much smaller than many other DSLRs).
The Olympus XZ-1 is excellent in bad lighting, but has a short zoom.
The Sony HX9V is one of the best video cameras around, and has a decent zoom as well, but it doesn't like dusk at all!
The 9V also takes really nice photos (as long as there is plenty of light), and the XZ-1 isn't too bad at video!
