AF auxiliary light projector for AF camera

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.
