Which Digital Camera is better ?

Which Digital camra is better than Sony DSC H5 in terms of features (Especially Digital Zoom while video shoot) and picture quality ... in the same price range

None of them. Sony currently makes the highest end ultrazoom camera with the most features and best picture quality (the DSC-H5). Note that digital zoom is not a good feature in a camera. It's the OPTICAL zoom that makes the H5 worth having. However, since this is a 7 megapixel camera, the digital zoom is actually useful as digital zoom works by blowing up a picture rather than magnifying it. Blowing up the picture results in loss of fidelity. Since the Sony has more megapixels than other ultrazoom cameras, you can do this more without degrading the shot too much.

try Cannon brands. i have two

i have a casio exilim ex z-850 and i am in love with it!!! it is so good and easy to use with tons of settings and it takes video and it is just amazing!!!!

Try Canon or Sony products because they have way better quality. I own a Sony Digital Camera and a Canon Video Camera. We've had the video camera for years and have never gotten any glitches. But I dont know about my camera since i just got it last month, but its running terrific!
