A lens apparatus includes a holding barrel configured to hold a lens, an operation member, an exterior barrel configured to hold the operation member rotatably around an optical axis, and a fixed barrel. When the holding barrel and the exterior barrel move in an optical axis direction relative to the fixed barrel, an imaging state and a retracted state are switchable. When the operation member is rotated in one direction in each of the imaging and retracted states, the operation member gets engaged with the fixed barrel and the state gets locked. When the operation member is rotated in the other direction around the optical axis, the operation member gets disengaged from the fixed barrel, and the imaging state or the retracted state gets unlocked and switchable.

Lens apparatus

A lens barrel includes a lens and a holding barrel configured to hold the lens. The holding barrel includes a holding unit configured to hold the lens, a plurality of adhesion portions at which the lens held by the holding unit is fixed to the holding barrel by an adhesive, and a plurality of caulking portions at which the lens held by the holding unit is fixed to the holding barrel by caulking the lens. Each of the plurality of adhesion portions and each of the plurality of caulking portions are spaced apart in a circumferential direction of the holding barrel, on a plane orthogonal to an optical axis of the lens.

Lens barrel, imaging apparatus, and imaging system

An image capturing apparatus includes a first mount portion and a first cylindrical member that has a color different from a color of the first mount portion and is disposed in a circumferential direction of the first mount portion, an accessory includes an exterior portion, a second mount portion, and a second cylindrical member having a color different from a color of the second mount portion and similar to a color of the first cylindrical member and disposed in a circumferential direction of the second mount portion, and in a state where the accessory is attached to the image capturing apparatus, reference surfaces of the first mount portion and the second mount portion are in contact with each other, and the first cylindrical member and the second cylindrical member are externally exposed regardless of whether the accessory is attached to or detached from the image capturing apparatus.

Adapter for camera lens

A lens apparatus includes a first cam follower engaged with a cam groove and a first rectilinear groove, and configured to move forward and backward in an optical axis direction of the lens apparatus with rotation of the cam barrel, a second movable member including a second cam follower engaged with the cam groove and a second rectilinear groove, and configured to move forward and backward in the optical axis direction with rotation of the cam barrel, a contacting member provided on the first movable member, and a biasing member configured to bias the contacting member. The contacting member includes a first contacting portion that contacts the second movable member, the second movable member includes a second contacting portion that contacts the first contacting portion, and at least one of the first contacting portion and the second contacting portion inclines to the optical axis direction.
