Metabones Micro Four Thirds MFT 4/3 mount to Canon EF lens adapter, perfect for use with Panasonic Lumix GH4 and Blackmagic cameras.
It allows Canon EF lenses to be used with Micro Four Thirds mount cameras with full electronic iris / aperture lens control from within the camera. It works so seamlessly, you control the Canon EF lens from within the camera settings, just like controlling a Canon EF lens on a 5D or C300, etc.
This adapter is the Speed Booster S version, it has an internal lens which increases the maximum aperture by 1 x stop. So whatever lens / aperture your are using, you gain 1 x stop of additional light, this is great for low light shooting. It also increases MTF and makes the lens you are using wider by a factor of 0.71. This adapter provides excellent results which are free from vignetting and lens distortion, very impressive!
It uses high performance 32-bit technology, it is fully electronic and is powered by the camera body.
