MetaBones Speed Booster Adaptor

Specialist accessory manufacturer Metabones and optics company Caldwell Photographics have jointly announced the 'Speed Booster', a lens adapter for APS-C and Micro Four Thirds mirrorless cameras that reduces the focal length by a factor of 0.71x and increases the maximum aperture by 1 stop. The Speed Booster also promises sharper images compared to using the lens with a simple adapter. The first version will allow use of Canon EF lenses on Sony NEX bodies, and will be available this month from Metabones' web site for US$599. Support for additional lens mounts (including Nikon F) and camera systems (including Fujifilm X and Micro Four Thirds) is also planned.
