Metabones Leica R Lens to Blackmagic Pocket Cinema Camera with Micro-4/3 Mount Speed Booster

The Metabones Leica R to BMPCC Micro-4/3 mount Speed Booster is built exclusively to adapt the Leica R Lens to Blackmagic Pocket Cinema Camera with Micro-4/3 Mount. It can only be attached to the Blackmagic cameras equipped with 4/3 mount and not to any other standard 4/3 cameras. It integrates  6-element optical design incorporated to the ultra-high index glass to gain the best optical performance. This speed booster not only increases the lens speed and field of view, it also increases maximum aperture by 1 2/3 stop together with the lens’ MFT and in the process reduces crop factor to 1.75x. It also features clickless aperture ring and a removable Arca-Type Tripod Mount.
