Abstract:
1. An optical apparatus comprising: a first focus detection unit that detects a focusing condition of an image forming optical system through a first focus detection method and outputs a first focus detection signal; a second focus detection unit that detects the focusing condition of the image forming optical system through a second focus detection method different from the first focus detection method and outputs a second focus detection signal; a focus adjustment unit that executes focus adjustment for the image forming optical system based upon either the first focus detection signal or the second focus detection signal; and a notification unit that includes a display member, and alters a focus detection method notification displayed at the display member in correspondence to the focus adjustment that the focus adjustment unit executes, wherein the notification unit provides a first notification when the focus adjustment unit executes the focus adjustment based upon the first focus detection signal and provides a second notification when the focus adjustment unit executes the focus adjustment based upon the second focus detection signal, the second notification including a reason why the focus adjustment cannot be executed based upon the first focus detection signal.
