I am an artistic-type person, but fairly new to the realm of photography. I have a Kodak DX7590 that has served me very well and taken beautiful pictures in the great outdoors for the last couple of years, but I've recently acquired a job that requires most of my picture-taking to occur indoors. The DX7590 is auto-focus only, and I think one of the greater flaws I've encountered with it is its near complete inability to focus in low or indoor lighting, even with updated firmware. As a result, several of the pictures I took last time were just out of focus enough to be frustrating, and I've decided to look into buying another camera to supplement this one. My dilemma is this: Do I go ahead and buy another $400-up camera like the DX and hope it functions better in low lighting (despite many reviews indicating the contrary) -- or do I buy a camera advertised as a party-type camera that's a little cheaper, but possibly better equipped to handle poor lighting and people moving all around? I have money to burn, but am limited in my knowledge of the technical aspect. Any advice would be appreciated, with camera model suggestions in particular very appreciated.
