I'm looking to buy a new camera and upgrade from my Dimage F100. The two areas I am most interested in are optical zoom and low-ish light performance. I take most of my pictures indoors (gymnastics events, etc) and of my kids. I'd like a camera with a decent optical zoom and one that will perform well where the lighting is mostly fluorescent and not outdoors bright. And I'd like to keep it under $400.
Any suggestions?
