Optical zoom : noun Definition: a tool which produces an image of lower or higher resolution.(Source: [|Dictionary.com]) optical zoom is accomplished by [|cropping] an image down to a centered area with the same [|aspect ratio] as the original, and usually also [|interpolating] the result back up to the pixel dimensions of the original. It is accomplished electronically, with no adjustment of the camera's optics, and no [|optical resolution] is gained in the process.

Optical zoom works the same way as a magnifying glass or a microscope. When you put a magnifying glass over an object and light passes up through the lens to your eyes, the curvature of the glass causes the light rays to bend and expand, thus spreading out the appearance of the detail on the object below and making it appear larger. Detail that may get lost or "swallowed" when light rays are more crowded together becomes more apparent. Instead of seeing a little, creepy bug beneath your magnifying glass, you can now see a BIG creepy bug, as well as all the joints on its legs, the texture of its wings, and the structure of its mouth parts( the spider is imaginary ofr those who are to slow to pick up) //this is video shot at 10x optical zoom at a distance of about 10 feet.//
