Jul. 1997
Nikon have launched the AF-S Nikkor 500mm f/4D IF-ED (ED-IF in U.S.A), a D-type*1 supertelephoto autofocus lens with built-in Silent Wave Motor.
The supertelephoto lens offers the same autofocus (AF) drive speed, AF tracking performance and AF drive noise reduction mechanisms as the AF-S Nikkor 300mm f/2.8D IF-ED and AF-S Nikkor 600mm f/4D IF-ED lenses.
The lens features very fast f/4 f-number. With the lens mounted on a Nikon SLR like the F5*2, built-in Silent Wave Motor drive keeps AF shooting virtually silent. Three ED glass lens elements are excellent at correcting aberration.
The lens' M/A control lets photographers switch instantly between manual and autofocus modes. A focusing limit switch, focus lock button, and other controls make it easy to operate.

*1) The "D" of D-type lenses refers to distance.
An internal encoder is linked to the lens focusing ring, and transmits the shooting distance to the camera body automatically.
*2) AF-S Nikkor lenses provide autofocus operation when mounted on the Nikon F5, Nikon F4-series, Nikon F90X/N90s*, or Nikon F90-series/N90*, or Nikon F70D Panorama/N70* 35mm (135) autofocus single-lens reflex cameras, or the Nikon PRONEA 600i/6i* Advanced Photo System (IX240) autofocus single-lens reflex camera.
* The Nikon N90s, N90, N70 and PRONEA 6i are the product names for the U.S. market.
*3) Lenses with normal optical glass suffer from increasing color aberration as focal length increases, causing color smear due to focal offset.
Nikon was the world's first camera lens maker to develop special low dispersion ED glass to reduce prismatic effect, and uses it in Nikkor telephoto lenses delivering unsurpassed performance.
