I have a small Olympus Stylus 710 that is 7.1 megapixel. I don't know anything about a camera lens but it says AF 3x optical zoom 6.5 - 19.5 mm 1:3.4 - 5.7.
I think it's really easy to use. I've had it for at least a year and accidentally found out that I can use it like mini-camcorder!
It even recorded sound.
