The Metabones Alpa Lens to Sony NEX Camera Speed Booster allows a full frame Alpa 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. The lens follows this tradition of uncompromising precision robust build quality and outstanding finish. It uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens.
Contrary to the popular trend of other factories using an aluminum ring painted black on the camera-body-side we instead take no short-cut but use precision-machined brass with chromium plating on both the camera-body and the lens sides of our adapters in order to ensure smooth mounting great appearance and durability.
The lens side of the adapter features a strong leaf-spring structure strengthening the adapter-lens connection and ensuring tightness of the lens in order to reduce wear and prevent focus errors and optical alignment issues from appearing.
