The Metabones Minolta MD Lens to Sony NEX Speed Booster is made of precision-machined brass with chromium plating on both the camera-body and the lens side of the adapter, 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.
Metabones uses matte-black treatment to keep internal reflection to a minimum in order to maintain the maximum optical quality possible with the lens. The following Minolta lenses are incompatible, unless the lens aperture levers are modified: Minolta MD 135 mm F 2.8, Minolta MD 135 mm F 3.5 and Minolta MD 35-70mm F4.
