A dual lens camera has a lens carrier with a shorter focal length lens and a longer focal length lens for alternatively positioning only one of the lenses at a picture-taking axis. A single aperture for each one of the lenses is movable forward and rearward along the picture taking axis. The lens carrier is movable forward and rearward along the picture-taking axis in unity with the aperture, and is movable relative to the aperture to position the shorter focal length lens at the picture-taking axis when the aperture is moved rearward along the picture-taking axis and to position the longer focal length lens at the picture-taking axis when the aperture is moved forward along the picture-taking axis.
