Within months of its announcement of the 85 million mark in January 2014, NIKKOR lenses in its many years of rich history and knowledge in optical technology, continues at a steady rate to mark its next production milestone. In addition to the 90 million milestone, the total production of NIKKOR lenses equipped with the SWM, an autofocus motor developed by Nikon, has reached its 50 million total mark. The achievement comes within eighteen years since the 1996 release of the Ai AF-S Nikkor 300mm f/2.8D IF-ED, one of the first lenses with the SWM. Nikon’s SWM converts “traveling waves” into rotational energy to focus the optics, which in turn provides for exceptionally quiet autofocus photography. All NIKKOR lenses for SLR cameras released since 2004 have been equipped with the SWM.
