ABSTRACT:
A photographic camera comprises a camera body, a lens carrier for an objective lens supported for movement outwardly and inwardly of the camera body between respective picture-taking and storage positions, and a lens cover supported for movement relative to the camera body between a covering position in front of the objective lens when the lens carrier is in its storage position and a non-covering position removed from the objective lens when the lens carrier is in its picture-taking position. According to the invention, the lens cover includes an elastic sheet-like piece located to deform over the objective lens when the lens carrier is in its storage position and the lens cover is in its covering position, whereby the lens cover is prevented from abrading the objective lens.
