Metabones Contax Yashica Lens to Sony Nex Camera Speed Booster (Black)
The
Contax Yashica Lens to Sony Nex Camera Speed Booster from
Metabones allows Contax Yashica lenses to be mounted to Sony Nex-Mount APS-C format cameras, increasing the angle of view and the maximum aperture of the lens by 1 f-stop. This photo accessory also comes with a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
The Speed Booster condenses light from the lens and projects it onto the APS-C sensor without vignetting; this allows the sensor to capture all of the lens' transmitted light and effectively produce full-frame coverage on non-full-frame sensors. A corresponding increase in the maximum aperture of 1 stop makes the lens more effective in low-light situations and able to create a shallow depth of field.
Metabones' Speed Boosters are made of machined brass, finished in satin black, the camera-body, and chromium-plated on both mounts to ensure smooth mounting and reliability.
Automatic diaphragm (AE metering) and other auto functions are deactivated while Speed Booster is attached.
