Metabones Speed Booster Ultra 0.71x Adapter for Nikon F-Mount Lens to Micro Fou

Description

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
