The ability to magnify your subject for close-ups, or pull back for wide shots. Most current cameras include a variable optical zoom lens.
A camera's CCD consists of millions of pixels, each one building up a tiny charge of electricity in response to the light it "sees." The more pixels a CCD has, the higher its resolution.
