ZF.2 with F bayonet for digital SLRs support all- important operations such as the automatic mechanisms for time, aperture setting and program thanks to its electronic interface (CPU).  

The 85/1.4 Planar ZF lens is a short, high speed tele lens for the exacting SLR photographer. It provides an unusually bright and clear image in the finder. Even at full aperture, it delivers top image quality. Its angle of view and exceptional performance make the Planar 85/1.4 ZF the lens of choice for portraiture on location or in the studio. Its shallow depth of field at wide apertures allows the use of selective focus to emphasize the primary subject by defocusing the background. The lens’s “bokeh” (the imaging of out-of-focus zones), resulting from optical design and the 9-blade iris, is outstanding. Geometrical distortion is imperceptibly low, allowing high quality documentation photographs, both analogue and digital.
