Metabones Canon EF Lens to BMPCC4K T Speed Booster ULTRA 0.71x

Professional Lens Adaptation for BMPCC4K

The Metabones Canon EF Lens to BMPCC4K T Speed Booster ULTRA 0.71x is a precision-engineered optical adapter designed specifically for the Blackmagic Pocket Cinema Camera 4K. Unlike standard Micro Four Thirds adapters, this Speed Booster features optics optimized for the unique filter stack thickness of the BMPCC4K sensor, ensuring maximum sharpness and contrast even at extremely wide apertures.

Advanced Optical Performance

Utilizing an advanced 6-element, 4-group design with ultra-high index tantalum-based optical glass, this adapter reduces the crop factor of the BMPCC4K while increasing the maximum aperture by 1 stop. The result is a significantly wider field of view and improved low-light performance. The optical design is so refined that it actually improves the MTF (Modulation Transfer Function) of the attached lens, making even high-end optics perform better.

Rock-Solid Mechanical Build

The Speed Booster ULTRA 0.71x includes a dedicated tripod mount designed to match the height of the BMPCC4K body perfectly. This allows both the camera and the adapter to be secured to the same quick-release plate for a stable, vibration-free setup. The electronic integration supports aperture control, EXIF data, and image stabilization for compatible Canon EF lenses.

Important Compatibility Note

This Metabones Speed Booster is designed exclusively for the Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). It is not compatible with other Micro Four Thirds cameras such as those from Panasonic, Olympus, or JVC due to the specific optical calibration for the BMPCC4K filter stack.
