Well , you probalby need a camera with IS ( image stabilizer ) Minolta and Canon seem to produce that . For example, Diamage 3 and Canon IS powershot. If possible, switch your camera to manual mode and adjust the camera to higher shutter speed. But, keep in mind that you 'll need enough light. Good luck.
I currently own an Olympus 2.1 MP camera that seems to have a long lag time between pressing the exposure button and the actual exposure. When I take photos of my daughter (7 yo) they are frequently blurry because she doesn't like to hold still. I'm thinking of getting a new 4 or 5 MP camera. Are there any cameras that are especially good at taking fast exposures and minimizing blur due to subject motion? Thanks.
