Abstract
A camera having a lens barrel housed therein includes a reflection optical member for reflecting a light beam incident along a first optical axis (O) from a subject so as to reflect the light beam toward a second optical axis (O) intersecting the first optical axis; a light-quantity adjusting member for adjusting the quantity of incident light from the subject; and a drive source for displacing the light-quantity adjusting member, in which by displacing the light-quantity adjusting member, the quantity of the incident light from the subject can be adjusted, and the light-quantity adjusting member is displaced in a direction substantially perpendicular to an optical axial plane inclusive of the first optical axis and the second optical axis so as to adjust the light-quantity.
