Abstract
A video still camera of the single lens reflex type is provided having a movable finder mirror for reflecting light passed through an objective lens, and a movable optical low-pass filter for preventing a light component having a spatial frequency lower than a predetermined value from being incident on an image receiving element. The finder mirror is located at a position in a photographing path through which photographing light passes when the camera is in a finder observation condition, while the optical low-pass filter is located at that position instead of the finder mirror when the camera is in a photographing condition. A driving device for selectively positioning either the finder mirror or the optical low-pass filter at the position is provided. The compactness of the video still camera is improved.
