What's the differance between optical zoom and digital zoom in the same camera?

    I'll simplify... optical is just that, a zoom created with the optics (zoom lens) of the camera. As the lenses are adjusted the object appears closer. As for digital, the basic optics (also a zoom lens) manipulates by use of electronic algorithms the lens to the zoomed version by artificially 'filling in' the spaces that would have been seen with the necessary pixels to complete the image. Bottom line is to find a camera with a good optical lens and sufficient zoom (either optical or digital) to capture your 'typical' photos. If you need to see this take the two cameras, and zoom to max on the same subject...look through them and you can see (or maybe not) any difference.

    Optical zoom is through the lens while digital zoom is through software extrapolation. In optical zoom, light rays are just bent like when using a magnifying lens to make the image larger. In digital zoom, the image is taken, broken apart then the computer guesses what colors are placed on the spaces between those pieces to make a larger image. Optical zoom is clean and sharp. Digital zoom is pixelated. When you buy a camera, the first thing you do is disable digital zoom then never think about it again until you buy another camera.
