摘要： A lens apparatus includes a first optical system, a second optical system, a first focus adjusting unit configured to simultaneously adjust focus of the first optical system and the second optical system, and a second focus adjusting unit configured to adjust a relative shift of focus positions of the first optical system and the second optical system. The first focus adjusting unit is connected to both the first optical system and the second optical system. The second focus adjusting unit is connected to one of the first optical system and the second optical system.

摘要： A lens apparatus (200) includes a lens (211R,211L) disposed closest to an object, a holder (212) holding the lens, a cover (213) having a first opening (213A) to expose the lens when viewed from an optical axis direction of the lens and being positioned with the holder in the optical axis direction, and an exterior member (204) having a second opening (204F) to engage with an outer diameter of the cover. A first gap in a diameter direction orthogonal to the optical axis direction formed between the holder and the cover is larger than a second gap in the diameter direction formed between the exterior member and the cover.
