Abstract
An optical apparatus that is easy to assemble and prevents occurrence of an assembling failure. The optical apparatus includes an operation ring part having at least a focus ring and a zoom ring arranged along an optical axis and are rotatable thereabout. Encoders detect rotations of the focus ring and the zoom ring, respectively. A transmission mechanism is moved in accordance with rotation of the zoom ring and transmits rotation of the zoom ring to the encoder therefor. A regulation member regulates a range of rotation of the zoom ring to a predetermined angle range. When assembling the operation ring part, the encoders are inserted from the same direction, and the encoder for the focus ring is disposed in a range excluding an angle range through which the transmission mechanism is moved when the zoom ring is rotated through the predetermined angle range.
