<p>PURPOSE:To facilitate arranging a photoelectric converting means by inserting the photoelectric converting means to the optical path of the light which is made incident on the photoelectric converting part of a focus detector through a photographic lens and performing photometry for exposure control in accordance with the luminous flux going to the focus detector. CONSTITUTION:A vacancy 30 surrounded with a mirror box bottom part 29 is formed under a space 25 in a mirror box. A photometric device 31 for exposure control, a visual field mask 32, a field lens 33, a mirror 34, an image separating prism 35, a stop 37, a refocusing lens 38, a mirror 39, and a CCD sensor 40 as the photoelectric converting part of the focus detector are arranged there. The refocusing lens 38 is so arranged that it focuses the light passing the visual field mask 32 onto the CCD sensor 40.</p> |
