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.
