About Metabones Adapter
A Metabones adapter may be needed if you have a DSLR camera and want to use a particular lens which uses a different mount system. The range of simple adapters covers all the likely combinations of lens and camera, as well as some obscure ones. Make sure the Metabones adapter you choose is suitable for your specific needs. The Metabones Smart Adapters are designed to create cross-compatibility across a wide range of camera bodies and lenses.
Metabones is an international photographic equipment company based in Hong Kong which specialises in camera lens mount adapters. Its engineering base is in Vancouver, while manufacturing is done in China. The company takes a pride in its fine workmanship and chooses to use precision-machined chrome-plated brass rings on both sides of its adapters, offering smoother mounting and greater durability compared to the more typical painted aluminium rings. All adapters are precision designed for strong, solid connection using a leaf-spring structure. A matte black internal surface keeps reflection to a minimum.
As well as equipment designed to manage the various different lens mount systems available, Metabones has created adapters which can actually boost the performance of your camera/lens combination. Created by highly-respected lens designer Brian Caldwell, its Speed Booster adapter is designed to also increase your maximum aperture, make the lens functionally wider and offer improved maximum transfer function, resulting in a picture Metabones describes as "brighter, wider, sharper". Improbable as this may sound, enthusiastic reviewers confirm the Speed Booster's ability to increase effective aperture, field-of-view, and some aspects of optical quality.
