Abstract
An optical filter, such as a low-pass filter, which is disposed between a photo-taking lens mounted on a mount part of the camera body having an image sensor disposed on an image forming plane and a main mirror disposed within the camera body, is held in position jointly by a holding member fixed to the lower end of a front aperture part of the camera body and an elastic member fixed to the rear side of the holding member with a resilient force applied to the optical filter. In mounting the photo-taking lens on the camera body, when an end part of the photo-taking lens comes to touch the optical filter, the optical filter is allowed to temporarily move to escape from the photo-taking lens and to come back to its original position upon completion of the lens mounting operation.
