Patent ID: 8094200

Claim:
A lens apparatus in which light entering a lens barrel from an external source is incident to an optoelectric converting element for image recording, the lens apparatus comprising: a filter frame configured to include a filter that absorbs a specific range of wavelengths of light passing through an optical path of the lens apparatus; a filter driving unit that moves the filter frame to position the filter at a first position that is on the optical path or at a second position that is away from the optical path; and a filter housing structure that establishes a filter frame moving region in which the filter frame is arranged and moves, and that blocks an incidence of light from a source other than the optical path to the filter frame moving region, wherein the lens barrel includes a plurality of lenses, and the filter housing structure is arranged between the lenses, wherein the filter housing structure includes: a first support unit that is provided in the lens barrel and supports the filter frame to be moveable, enabling insertion and removal of the filter with respect to the optical path, and a second support unit that is provided in the lens barrel, forms a space with the first support unit, and supports the filter frame to be moveable in the space, enabling insertion and removal of the filter with respect to the optical path.
