A self-contained multiple objective lens camera includes a pair of objective lenses and a manually operable mechanism for alternatively selectively positioning either of the lenses in registry with the camera photographic optical axis and the respective other lens offset from the axis. A manually operable distance setting device is located on the camera body and each lens includes a driven follower which adjusts the focus of the respective lens and is in and out of operable engagement with the setting device when the lens respectively registers with and is offset from the photographic optical axis. Accordingly, the optical axis registering lens is focussed in accordance with the presetting of the distance setting device and transfer of the lenses to optical axis registry without changing the distance setting focusses of the lenses when at the optical axis to the same distance.
