Leica R to BMCC Speed Booster (Black Matt) Metabones

Podrobný popis

The Metabones Leica R to BMCC Speed Booster (Black Matte) is a specialized adapter for Blackmagic Cinema Cameras with Micro-4/3 mounts, enhancing lens performance by reducing crop factor and increasing lens speed for Super-35 cine-quality footage.

The Metabones Leica R to BMCC Speed Booster (Black Matte) is engineered exclusively for the Blackmagic 2.5K Cinema Camera (BMCC) with a Micro-4/3 mount. This 0.64x Speed Booster adapter transforms the BMCC’s full-frame crop factor from 2.39x to a cinematic Super-35 equivalent of 1.53x, offering filmmakers a broader field of view and enhanced performance. By attaching a Leica R-mount lens, users gain 1⅓ additional stops of light, allowing for a maximum aperture output of f/0.80, perfect for low-light cinematography and achieving a shallower depth of field. For example, a 50mm f/1.2 lens adapts to become a 32mm f/0.80, while a Sigma 18-35mm f/1.8 is transformed into an effective 11.5-22.5mm f/1.1.

Designed with cine-quality shooting in mind, this Speed Booster adapter provides more flexibility for videographers and photographers, allowing Leica R-mount lenses to achieve wider views and faster speeds, creating professional results directly on Blackmagic’s 2.5K Cinema Camera. Note: This adapter is exclusive to Blackmagic Micro-4/3 mount cameras and is not compatible with standard Micro 4/3 cameras.
