Mounting between a mirrorless camera and an SLR lens, the Speed Booster adapter from Metabones and Caldwell Photographic increases maximum aperture by a full stop (hence its name) and has a focal length multiplier of 0.71x. This essentially means that full-frame SLR lenses can be used on a compact system camera with an APS-C sized sensor with (almost) the same angle-of-view coverage as originally designed. For example, a 28mm lens becomes a 19.9mm with the Speed Booster - if you then mount it on a camera with a 1.5x “crop factor” you’ll end up with a 29.8mm equivalent solution. The first Speed Booster enables users to mount Canon EF lenses to Sony NEX bodies, with auto-aperture, image stablisation, EXIF and (slow) autofocus support for post-2006 Canon-brand lenses. It will be available in later this month from Metabones’ website and its worldwide dealer network for $599 plus shipping and applicable taxes and duties.
