摘要： An AF auxiliary light projector for an AF camera includes a focus detection optical system having a first optical axis, and an AF auxiliary light projecting optical system having a second optical axis which intersects the first optical axis, the AF auxiliary light projecting optical system projecting an image having a predetermined contrast pattern onto an object. The AF auxiliary light projecting optical system includes a projector lens, a contrast pattern chart, an illumination lens, and an illumination light source, in that order. The illumination lens has an asymmetrical optical power so that an optical power of a far distance portion of the illumination lens for a far distance region of the contrast pattern chart is greater than an optical power of a near distance portion of the illumination lens for a near distance region of the contrast pattern chart.

摘要： A photographing apparatus comprises an imaging sensor, a controller, and an exposure-mode-selecting device. The controller performs a photometric operation on a photographing subject and obtains a luminance value of the photographing subject based on the photometric operation. The exposure-mode-selecting device is used for selecting an exposure mode of the photographing apparatus that has a sensitivity priority AE mode. The photographing operation is performed with a sensitivity of the imaging sensor that is set by a user and a shutter speed and an aperture value that are calculated based on the luminance value and the sensitivity, while the photographing apparatus is in the sensitivity priority AE mode.
