The present invention relates to a lens or objective for a camera, more particularly for a digital camera, comprising a housing, an actuating element arranged on the housing, and a lens element system that can be set into a plurality of settings, wherein the lens element system is embodied in such a way that in at least one setting an f-number is F≦3. The lens element system is furthermore embodied in such a way that an actuation of the actuating element brings about a movement of two optical elements relative to one another, such that an intersection length difference of the lens element system can be set.
