Optical apparatus, imaging apparatus, and control method |
摘要 |
An optical apparatus includes a control unit configured to perform an operation for moving a focusing lens at a first speed to detect a first position corresponding to an in-focus state and then moving the focusing lens at a second speed lower than the first speed in forward and backward directions across the first position to detect a second position corresponding to an in-focus state, and an output unit configured to output information indicating an in-focus state of the focusing lens recognizable by a user. The output unit outputs the information in response to the control unit detecting the first position.
