The Metabones EF lens to Micro Four Thirds body Speed Booster "S" version allows you to use a full frame Canon EF lens on a M43 body camera and still be able to control the lens electronically, also giving you an extended field of view and an extra stop. The angle of view is increased by 0.71x. Thanks to the Metabones EF to Micro Four Thirds Speed Booster, the crop factor that you experience when shooting on a M43 camera is greatly reduced and the sensor of your camera is able to use all of your lenses' light. If you're using a Canon lens with IS, the image stabilization is preserved with this speed booster adapter and also all the EXIF data are transfered. This Metabones Speed Booster is powered by your camera and features a 32-bit processor.
