Metabones Contarex to Xmount Speed Booster 0.71x (Black Matt)

The Contarex Lens to Fuji X Camera Speed Booster from Metabones allows Contarex lenses to be mounted to Fuji X-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.
