A unique, compact telephoto lens that gives the choice of razor-sharp images, or with the twist of a ring, two degrees of soft focus. It works by applying “softness over sharpness,” using deliberate spherical aberration on top of a sharp “core” image at apertures from f/2.8 thru 5.6; images taken at apertures smaller than f/5.6 are always sharp. Autofocus continues to function, with or without the soft focus in use. This lens is an ideal addition to a portrait or scenic photographer’s arsenal. A perfect combination with an EOS Digital SLR, with the camera enabling review of soft focus effect on the LCD monitor.
