Abstract:
1. A camera including a lens barrel having a reflection optical member for reflecting a light beam incident along a first optical axis from a subject so as to reflect the light beam toward a second optical axis intersecting the first optical axis, the lens barrel comprising: a lens group arranged along the second optical axis; a holding frame for holding the lens group movably along the second optical axis; and shutter means moving integrally with the holding frame and including a shielding member movable between a position masking an exposure opening on a plane substantially perpendicular to the second optical axis and a position opening the exposure opening, wherein the shielding member is linearly moved in a direction substantially perpendicular to an optical axial plane inclusive of the first optical axis and the second optical axis, said light-quantity adjusting member being movable in a second plane parallel to the first optical axis and orthogonal to the second optical axis.
