Why do cheaper camcorders have higher zoom? You may wonder why a high end camcorder has a 10x zoom, and a cheaper camcorder a 25x zoom. The answer is the imager size. Two camcorders with the same lens, but one with an imager half the size of the other will have double the zoom. While you may gain in the amount of zoom, you lose in image quality and low light capability with a smaller imager.

These programs employ a modified version of to deliver the courses. Recordings of MAT student work are posted on USC's for evaluation by as if they were present in class. Camcorders have allowed USC to decentralize its teacher preparation from to most American states and abroad; this has increased the number of teachers it can train.
