A lens assembly comprises a lens group M and a lens framefor retaining the lens group M. In this lens assembly, the lens framehas an entire circumference supportfor supporting the rim on the subject side, of each lens M, across the entire circumference thereof, and an end face supportfor supporting the lens M on the image side. Each lens M comprises a chamferformed at a rim of a lens surface on the subject side across the entire circumference thereof, and the entire circumference supportsupports the chamfersuch that the entire circumference supportis continuous with the lens surface at substantially the same radius of curvature with the lens surface. According to the present invention, there is provided a lens assembly which can reduce size and cost and has stable lens retaining ability.

To provide a data imprinting device for a camera which has a simple construction and does not make the main body of the camera large in size, a data imprinting device for a camera includes: an LED for optically generating data to be imprinted on a film surface; a prism for allowing data light generated by the LED to form an image on the film surface; a holder for holding the LED and the prism and disposed in such a manner as to be movable in a direction perpendicular to an optical axis for photographing of the camera; and data-imprinting-position changing means for moving the holder in interlocked relation with a changeover of a photographing image size on the film surface, and for changing a position of imprinting data on the film surface.
