Faster, Wider, Sharper! Metabones, announces the Speed Booster, the full frame lens adapter for a mirrorless camera that promises wonders, and it ain't 1st of April yet

Metabones and Caldwell Photographic introduce Speed Booster

Petersburg, VA, USA, January 14, 2013 - Metabones® and Caldwell Photographic jointly announce a revolutionary accessory called Speed Booster™, which mounts between a mirrorless camera and a SLR lens. It increases maximum aperture by 1 stop (hence its name), increases MTF and has a focal length multiplier of 0.71x. For example, the Canon EF 85mm f/1.2L II lens becomes a 59mm f/0.9 lens on a Sony NEX camera, with increased sharpness. The faster F-stop allows for shallow depth-of-field and a lower ISO setting for decreased noise. . . . read more
