If you are looking for a excellent, very compact camera with 7.2 megapixel sensor, 3x optical zoom, 2.5 inch LCD, that produces good images and excellent battery life. That is about the size of a deck of cards then you should consider the Sony Cyber-shot DSC-W70
Ben of Digital Camera Review reviewed the Sony Cyber shot DSC-W70 and says this:
The Sony Cyber-shot DSC-W70 is a stylish, compact camera that takes great pictures. With its 7.2 megapixels, you get plenty of resolution even if you have to crop out some bad areas of your image. The 3x optical zoom is pretty standard these days, but it helps you get a little closer. The very nice 2.5 inch LCD doesn't have a ton of resolution (115K pixels), but it's very bright and easy to see, even on bright sunlit days.
Images are sharp, colors are good, and the camera handles tough lighting conditions well. It also does a good job of flash-lit indoor shots, a place where many consumer digital cameras do poorly.
Battery life was very good. I took 100-150 shots under normal use while I gathered sample images. Then, in an attempt to discharge the batteries, I hit the 300 image mark with the flash shooting each time. After the 300th image, I gave my finger a break. The camera still had plenty of juice to keep going. Sony's claim is 390 images, so I think under normal use, you will probably get between 300 and 390 shots.
The W70 is a great camera for someone looking for a stylish camera that takes good pictures under a variety of conditions. Outdoor shots are very good and the camera has good indoor performance. The excellent LCD and ease of use also make this a very attractive camera to photographers who don't need a ton of features. Sony chose wisely on which modes to include and kept the list down to just enough, but not too much to easily change with the mode dial. Read the entire review
