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

Professional Optics for Blackmagic Pocket Cinema Camera 4K

The Metabones Canon EF to BMPCC4K Speed Booster ULTRA 0.71x is a precision-engineered adapter designed specifically for the unique sensor requirements of the Blackmagic Design Pocket Cinema Camera 4K. Unlike standard Micro Four Thirds adapters, this CINE version features optics optimized for the 2.4mm filter stack found in Blackmagic cameras, ensuring superior image quality and sharpness across the frame.

Enhanced Light and Field of View

This Speed Booster reduces the crop factor of the BMPCC4K from 2.02x to 1.43x, effectively transforming the sensor field of view to a Super 35 format. By concentrating light from full-frame Canon EF lenses, it increases the maximum aperture by one stop, reaching a record-breaking f/0.9. This makes it an essential tool for low-light cinematography and achieving a shallow depth of field.

CINE Positive Locking Mechanism

Built for demanding film sets, the CINE version is equipped with a robust positive locking mechanism. This breech-lock style mount ensures that lenses are held firmly in place with zero play, which is critical when using follow-focus systems or heavy cine-modified EF lenses. The electronic integration allows for seamless control of lens aperture and image stabilization directly from the camera body.

• Optimized Optics: Specifically tuned for the 2.4mm filter stack of the BMPCC4K.
• Increased Speed: Boosts maximum aperture by 1 stop for better low-light performance.
• Wider Perspective: Reduces crop factor to 1.43x for a Super 35 look.
• Rock-Solid Mount: Positive locking mechanism eliminates lens play during focus pulls.
