Abstract
For use with a camera which is adapted for use with at least two interchangeable lenses having different brightness levels, a switching assembly is provided to enable one of at least two focussing, photosensitive elements each associated with a different one of the lenses. The switching assembly comprises first means normally assuming a first predetermined position in which one of the elements is enabled for operation, said one element being effective to detect an in-focus position when a corresponding interchangeable lens is mounted, and second means adapted to be forcibly displaced from a position in which said one element is enabled to another position in which the other element is enabled for operation.
