1. A lens apparatus comprising:
a lens disposed closest to an object;
a holder holding the lens;
a mount for attaching the lens apparatus to an imaging apparatus;
a circuit board configured to communicate with the imaging apparatus; and
a base member where a first optical system, a second optical system, and the circuit board are attached,
wherein the lens has a first lens included in the first optical system and a second lens included in the second optical system,
wherein each of the first optical system and the second optical system is a bending optical system having a first reflective surface and a second reflective surface, and includes, in order from an object side, a first optical axis, a second optical axis of light reflected by the first reflective surface, and a third optical axis of light reflected by the second reflective surface,
wherein at least a part of electric elements provided on the circuit board is arranged inside a diameter of the mount when viewed from the axis direction of the mount, and
wherein the first optical system, the second optical system, and the circuit board can move integrally with the base member in a first optical direction relative to the mount.
