Auto Focus Lenses
An auto focus lens requires one or more sensors in order to properly determine the accurate focus of the shot. Often times with modern cameras, the auto focus feature is so precise, it works more reliably than a camera that necessitates a manual operation to bring objects into focus. There are two basic types of auto focus: active and passive. With active auto focus, the systems keep track of the distance to an object separate from the optical system, which then adjusts the systems for proper focus. Passive focus records inert analysis of the subject in the optical system, but do not register any light waves toward the object being photographed. The biggest downfalls you will find with auto focus lenses are that it is much more difficult to photograph through windows and focus on an object that is too close to the camera.
