A camera comprises a lens tube having a plurality of tube frames of different inner diameters, the plurality of tube frames moving between a collapsed position and a photographing position, and a lens barrier movable between a covered position and an exposed position, in which in a state of the lens tube being housed in the collapsed position, a shape of an outer peripheral surface of a tip portion of a first tube frame positioned closest to an optical axis becomes larger in the diameter as it is closer to a photographer side along the optical axis, and a position of a tip portion of a second tube frame having a larger diameter than an outer diameter of the first tube frame is positioned at the photographer side rather than the maximum diameter portion of the outer peripheral surface of the tip portion of the first tube frame.
