A taking lens of a camera includes first and second lens elements. A lens holding frame retains the first lens element on a lens base or a front surface of a shutter unit. In the lens holding frame, a holding frame body is disposed in front of the first lens element. Arm portions are formed to project from a periphery of the holding frame body, have a distance to the lens base when in a free state, are bent resiliently by a retention pin or screws, and are secured to the lens base. Thus, the first lens element is squeezed tightly between the lens base and the holding frame body.
