"The ZEISS ZF.2 with F bayonet for digital SLRs. Thanks to its electronic interface (CPU), these new ZEISS lenses support all-important operations such as the automatic exposure for shutter priority, aperture priority and program modes. The CPU also supports manual exposure settings, including those for camera casings that are not AI-compatible. Since the lens now transmits the EXIF data such as manufacturer, date, metering system and exposure settings, photographers no longer need to set the parameters manually. These quicker and faster handling capabilities of the ZF.2 lenses are especially useful under hectic shooting conditions. ZEISS lenses truly come into their own in situations that demand extreme photographic creativity and maximum image quality. Carl Zeiss' fixed focal length lenses are known for their high light sensitivity and precise manual handling, leaving the photographer in full control. The new ZF.2 series will be especially interesting for photo enthusiasts who value creative, high-quality images combined with the comfort of automatic settings.|The lens' shallow depth of field at wide apertures allows the use of selective focus. This helps to emphasize the primary subject by defocusing the background.|The 9-blade, circular aperture produces a smooth and natural rendition of defocused images, as well as nearly circular shapes of point sources of light.|Geometrical distortion is imperceptibly low, allowing high quality documentation photographs, both analog and digital."
