Metabones has been designing and manufacturing lens adapters recognized among professionals and enthusiasts as leaders in design and workmanship. The Metabones Speed Booster Ultra 0.71x Adapter for Nikon F-Mount Lens to Micro Four Thirds-Mount Camera is used for a full-frame or APS-C Nikon F-mount lens to mount on a Micro Four Thirds-mount camera. In addition to conversion, the optics of the adapter help to maximize the lens's apparent angle of view while providing a 1-stop increase for the camera over the lens's aperture range. The Speed Booster Ultra 0.71x Adapter for Nikon F-Mount Lens to Micro Four Thirds-Mount Camera condenses the light from a lens designed for APS-C as well as 35mm film, or "full frame" camera sensors and projects it onto a Micro Four Thirds sensor. It helps a Micro Four Thirds sensor to utilize more light, which effectively reduces the crop factor while making available to the sensor an additional 1 stop of light for each of the lens's f/stop settings. The adapter is made of aluminum alloy for extended durability while benefiting with reduced weight whereas the mounting rings are made from brass to get prevention against wear-and-tear. The optics are arranged in five lens elements in four groups to provide optical clarity as well as color fidelity, and a detachable tripod foot is included that features a 3/8" threads as well as compatibility with Arca-Swiss tripod heads. The speed booster does not support electronic communication between an attached camera and lens. To determine the amount of light that enters a Micro Four Thirds-mount camera while using this adapter and a Nikon F-mount lens, an aperture dial is designed to provide aperture control for Nikon G-type lenses, which do not have an aperture ring.

Features:
  • Industry's best aperture ring covers a 8-stop range, clearly indicating actual number of f-stops. No more guesswork! (Patent pending).
  • Compatible to both Nikkor G lens & F lens (include non-AI & AI lens mounts).
  • Increase maximum aperture by 1 stop.
  • Increase MTF.
  • Makes lens 0.71x wider.
  • Optics designed by Caldwell Photographic in the USA (patent pending).
  • The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo Clam ball heads.
