Abstract
A simple focusable lens combination of a camera including a housing formed with a lens hole. A photosensor and a base board are disposed in the housing. The base board is movably disposed in the housing. Multiple lenses with different focal lengths are disposed on the base board. By means of moving the base board, one of the multiple lenses is selected to aim at the lens hole for focusing images of different distances onto the photosensor.
