The Metabones Nikon F Lens to Sony NEX Camera Speed Booster allows a full frame Nikon G lens to be mounted to an NEX APS-C format camera and in doing so, increases the angle of view and increases the maximum aperture one f/stop
When a lens intended for full frame sensors or 35mm film is mounted to a camera with an
APS-C sized sensor, it transmits a larger area of light than the smaller sensor was built to accept and therefore
the effective angle of view of the lens decreases and the equivalent focal length increases.
The Speed Booster condenses light from the lens and projects it onto the APS-C sensor to
utilize all of the lens' light and effectively produce a full-frame angle of view with an APS-C sensor. A
corresponding increase in the maximum aperture of one f/stop makes the lens more effective in low-light situations
and create a shallow depth of field.
Metabones Speed Boosters are
quality made, using precision-machined brass with chromium plating on both the camera body and the lens side of the
booster in order to ensure smooth mounting, quality aesthetic, and durability.
This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and
Photo Clam ball heads.
Although the lens will fit physically,
automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster. The Nikkor
2.1cm f/4 and 20mm f/2.8 AI-S lenses are not compatible with the speed booster.
