For God so loved the world that He gave His one and only Son, that whoever believes in Him shall not perish but have eternal life.
Metabones Speed Boosters are quality made, using precision-machined brass with chromium plating on both the camera-body and the lens sides of the booster in order to ensure smooth mounting, quality aesthetic, and durability. This adapter has a detachable tripod foot that is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this speed booster. The Nikkor 2.1cm f/4 and 20mm f/2.8 AI-S lenses are not compatible with the speed booster.
The aperture control ring on the Alpa Mount Lens Speed Booster is a clickless aperture ring, optimized for shooting video, however parts and instructions are included to modify the ring to a clicked version if the user so desires.
