ABSTRACT:
A camera which includes a camera body, a rear cover, and a diopter adjusting mechanism having a diopter adjustment lens for a finder optical system, including: a diopter adjustment knob provided on the rear cover; a transmission member connected to the diopter adjustment knob so as to relatively move in the direction along the axis of rotation of the knob and not to relatively rotate thereto ; a biasing spring which biases the transmission member to project toward the camera body side; a lens association rotation member which is supported by the camera body so as to rotate about an axis identical to the axis of the knob and which moves the diopter adjustment lens in the optical axis direction, in accordance with the rotation of the lens association rotation member; and at least one rotation transmission projection and recess provided on one and the other of the transmission member and the lens association rotation member; the transmission member projects to a projected position close to the camera body when the rotation transmission projection engages with the rotation transmission recess, and is retracted to a retracted position in the rear cover when the rotation transmission projection does not engage with the rotation transmission recess.
