Optical zoom is ‘real’ zoom.
digital ‘zoom’ is actually more like a “cropping” feature. Useful to tighten in your auto-focus points, if you shooting something quite distant, with an assortment of closer objects … but not a ‘true’ zoom.
More optical zoom, is always the important number, in terms of ‘zoom’ … however, more optical zoom requires more “stabilization” inside the camera.
As far as mega-pixels … on a pocked sized point-and-shoot … everything above about 7MP is actually ‘computer generated’ inside the camera. The “sensor plate” (“electronic-replacement-for-film thingee” is the technical term)can only be ‘so big’ to fit inside that little bitty box … so, the rest of the pixels are … sorta ‘guessed at’ … guessed at very well, mind you … but if you really want/need 14MP, because you’re going to be printing professional posters or wall-sized murals … you need a DSLR.
14MP in a pocket-point-and-shoot, is pretty much lots. The size of those files will actually send you to the software, to make them smaller so you can send more than one at a time to Grandma.
(none the less, always shoot at your highest … or you’ll get your ‘shot of a lifetime’ on some small setting and kick yourself.)
