Metabones Speed Booster Ultra 0.71x Cine Adapter for Contax/Yashica-Mount Lens to Micro Four Thirds-Mount Camera

The Speed Booster Ultra 0.71x Cine Adapter from Metabones allows a Contax/Yashica-mount lens to be used a Micro Four Thirds-mount camera. The adapter's optics maximize the connected lens's apparent angle of view by a factor of 0.71x while providing a one-stop increase for the camera over the lens's aperture range. This adapter condenses the light from a lens designed for 35mm film cameras and projects it onto the Micro Four Thirds-size sensor. This allows the camera's sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional one f/stop of light for each of the lens's f/stop settings.

This adapter is constructed from aluminum for durability while minimizing weight, and its mounting rings are made with brass to further prevent wear and tear. The internal optics feature five lens elements in four groups and are designed to provide optical clarity as well as color fidelity. The detachable tripod foot is Arca-type compatible and features 1/4"-20 threads

NOTE: Not compatible with the Contax 15mm f/3.5 Distagon T* lens.
