摘要： A digital single-lens reflex camera includes a first mirror for reflecting part of a light beam coming from a subject through a photographing optical system and transmitting the remaining light beam. The reflected light beam is used for detecting the focus state of an imaging light beam, and the transmitted light beam is used for performing live view display. For example, the first mirror can be configured as a movable mirror in the digital single-lens reflex camera. This enables continuous live view display using the transmitted light beam on condition that the movable mirror is down while detecting the focus state using the reflected light beam. In addition, phase-contrast AF can be adopted for detecting the focus state.

摘要： In a camera having a camera body unit constituted by combining a plurality of units, the camera configuration is realized so as to allow to easily remove only a lens frame unit from the camera body unit before the other units (for example, a strobe unit, a finder unit, a film feed unit and the like) when the camera is disassembled to repair or replace the lens frame unit by constituting so that the lens frame unit having a photographing optical system can be mounted independently.

摘要： The present invention provides a camera having a film feed mechanism comprising a microphone for sensing the surrounding noise around the camera, a noise level measuring portion for measuring the sensed noise (sound pressure), a noise level discriminator for comparing the measured noise level with a predetermined level to discriminate whether the measured noise level is higher or lower than the predetermined level, a feed mode change-over portion for changing the film feed speed to a silent mode or a normal film feed by selecting the normal film feed or the film feed whose generated noise level is low in response to the discriminated noise level, and a film feed mechanism for feeding a film in both winding and rewinding.
