Metabones Speed Booster Micro 4/3 to Contax/YASHICA

The YASHICA contax lens for Micro Four Thirds camera mount Speed Booster from Metabones allows a full frame Contax lens to be mounted on a Micro Four Thirds camera mount and, in doing so, increases the angle of view and increases the maximum f/stop aperture YASHICA to be mounted on a Micro Four Thirds mount camera and, in doing so, increases the angle of view and increases the maximum f/stop aperture .

When a lens intended for full frame or 35mm film sensors is mounted on a camera with a Micro Four Thirds size sensor, it transmits a larger area of light than the smaller sensor was built to accept and, therefore, the angle of view of the lens decreases and the equivalent focal length increases. The Speed Booster condenses the light from the lens and projects it onto the smaller sensor allowing the sensor to utilize all of the lens ' light and effectively produce a full-frame angle of view with an MFT sensor. A corresponding increase in maximum aperture of one f/stop makes the lens more effective in low light situations and capable of creating a depth of field.

Metabones SpeedBoosters are quality made, using precision machined brass with chrome plating on both the camera body and the sides of the lens for dose reinforcement in order to ensure a smooth mount, quality aesthetics , and durability. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins and ball heads.

Although the lens physically fits, automatic aperture (AE metering), or other auto functions are not retained using this speed booster. Micro Four Thirds speed boosters are shipped with a Silent Switch ring that can be easily converted to a clicked ring without additional parts.
