Abstract
A camera includes a zoom lens which has a group of variable power lenses for changing the focal length thereof, a variable illumination angle strobe device which has an illumination angle varying mechanism having a condenser lens, a light emitting tube and a light reflecting shade which are relatively movable in the optical axis direction to change the illumination angle. The illumination angle varying mechanism includes a device for controlling the illumination angle in association with the focal length of the zoom lens and a device for controlling the illumination angle independently of the first mentioned device.
Claims22
A camera comprising a zoom lens which has a group of variable power lenses for changing the focal length of said lens, a variable illumination angle strobe device which has an illumination angle varying mechanism having a condenser lens, a light emitting tube and a light reflecting shade, said condenser lens, said light emitting tube and said light reflecting shade being relatively movable in the optical axis direction to change the illumination angle of said strobe device, wherein said illumination angle varying mechanism comprises association means for controlling the illumination angle in association with the focal length of the zoom lens and an independently driven means for controlling the illumination angle independently of the association means.
