"If you need a small camera they don't come any smaller than the Pentax Optio 330. The Optio 330 makes a great "go anywhere and be ready at a moment's notice" kind of camera due to its very pocketable size and light weight. Overall the image quality is very good. The lens produces sharp images and the autofocus is fairly quick in average lighting. One of the problems of a small camera is an equally small battery. Even with very conservative use of the LCD the battery doesn't go all that far, I'd estimate maybe 60 to 70 shots per charge. . It's all about tradeoffs so if you're willing to put up with a few less than perfect things to have a highly portable camera then go for it or else look at one of the mid-sized cameras instead."
