The Metabones EF to E-Mount Speed Booster provides an excellent solution for those looking to use Canon EF lenses on Sony E-Mount camera bodies. The conventional Metabones adapter has been hugely popular with users of the Sony FS700, enabling use of the enormous Canon EF lens range. Not only does the Speed Booster provide full functionality as per the earlier adapter, but has a few excellent features of its own. Primarily, this adapter not only increases apparent lens sharpness, but offers a 0.71x crop factor enabling more efficient use of wide angle lenses on a crop sensor.
Above all else though, this handy piece of kit allows any given lens to gain an additional stop of light when mounted to the adapter. For example turning a 70-200mm f/2.8 zoom lens into an f/2 maximium aperture lens, a significant increase – especially for light strained situations that demand shooting at the widest possible aperture. The Metabones Speed Booster is available for rental at Camera Hire now, and can be packaged with Canon lenses or the Sony FS700 kits to suit a number of shooting requirements
