To provide optical equipment capable of performing focus detection of a time series pupil partitioning system with compact constitution by easy operation.

The optical equipment has a light shielding member 31 where an aperture 31a is formed, and a driving means which moves the light shielding member so as to form a first aperture and a second aperture, positionally different from the first aperture in a direction orthogonal to an optical axis, through which luminous flux used for focus detection passes. The first and the second apertures include an area S including an optical axis position AXL common to each other.
