Metabones EF To M4/3 Mount Speed Booster

Description

This adapter lets Canon EF-mount lenses be used on Micro Four Thirds cameras while also increasing light transmission and reducing the effective focal length, thanks to its internal Speed Booster optics. It's used to gain roughly one extra stop of light and a wider effective field of view compared to a standard, optics-free EF-to-MFT adapter, compensating for the smaller MFT sensor size. Its internal lens elements focus the EF lens's image circle down to properly cover the Micro Four Thirds sensor. It's compatible with MFT-mount cameras such as the Blackmagic Pocket Cinema Camera in our fleet. It suits productions using EF-mount lenses on MFT cameras that want extra low-light performance and a wider field of view.
