摘要： A lens apparatus includes a first optical system, and a second optical system disposed in parallel with the first optical system. Each of the first optical system and the second optical system includes, in order from an object side to an image side, a first optical axis, a second optical axis, and a third optical axis. When each of the first optical system and the second optical system rotates around an axis parallel to the third optical axis, a distance between first optical axes of the first optical system and the second optical system changes greater than a distance between third optical axes.

摘要： A lens mount includes a cover member and a holder. The cover member has a first opening corresponding to a first optical system of a lens apparatus and has a second opening corresponding to a second optical system of the lens apparatus. The holder holds a filter to cover the first opening and the second opening. The holder includes a first holder disposed on one side with respect to the first and second openings in a direction orthogonal to an arrangement direction of the first and second openings, and a second holder disposed on the other side with respect to the first and second openings in the direction orthogonal to the arrangement direction. A groove portion is formed between the cover member and the holder, and the filter is insertable into the groove portion.

摘要： A light amount adjusting device includes ND filters rotating around shafts serving as rotation shafts and moving between in-use positions and retracted positions, arranged on a base plate. The respective ND filters include uniform density portions, gradation portions, and transparent portions. If the ND filters are in the retracted positions, the transparent portions of the respective ND filters overlap in an area facing an aperture to cover the entire aperture with the transparent portions. If the ND filters are in the in-use positions, the gradation portions of the respective ND filters overlap in an area facing the aperture to cover the entire aperture with the gradation portions and the uniform density portions. Moreover, a combined density acquired when the gradation portions overlap in just proportion is substantially the same as an optical density of each of the uniform density portions.

摘要： A lens barrel having a holder member that holds an imaging device package and allowing one or more structure members other than the holder member to be disposed around the package. The imaging device package in which an imaging device is housed is held by the holder member having planar portions that are disposed parallel to the package and that are coupled to each other through raised bent portions. The raised bent portions of the holder member are disposed so as to be overlapped with and inside the package as seen from an optical axis direction, thereby obtaining a free space around the package, in which one or more structural members other than the holder member can be disposed.
