Metabones Canon EF Lens to Micro Four Thirds T CINE Speed Booster ULTRA 0.71x

Professional Cinema Integration for MFT Systems

The Metabones Canon EF Lens to Micro Four Thirds T CINE Speed Booster ULTRA 0.71x is a high-performance electronic adapter designed to bridge the gap between Canon EF-mount glass and Micro Four Thirds (MFT) cameras. This fifth-generation model features a robust positive-lock lens mount, ensuring a secure, wiggle-free connection essential for follow-focus systems and professional cinema workflows.

Advanced Optical Performance

Utilizing custom optics, this Speed Booster reduces the crop factor of MFT sensors by 0.71x, effectively widening the field of view. Simultaneously, it increases the maximum aperture of your lens by approximately 1 stop, providing superior low-light performance and shallower depth of field. The internal design features black felt flocking to eliminate internal reflections and maintain maximum contrast.

Seamless Electronic Communication

Equipped with a high-performance processor, the adapter supports critical electronic functions:

• Autofocus and Iris Control: Adjust aperture directly from the camera body with support for smooth iris effects on select lenses.
• Image Stabilization: Full communication with in-lens IS and support for 5-axis in-body stabilization.
• Exif Data: Transmits focal length and aperture information for accurate metadata recording.
• Cinema EOS Support: Compatible with Cinema EOS lenses when powered via the integrated micro-USB port (5 VDC).

Rugged and Weather-Resistant Design

Built for the field, this adapter includes a rubber gasket to protect the camera mount from dust and moisture. For heavy lens setups, the removable Arca-type compatible tripod foot provides a stable mounting point with a standard 1/4"-20 thread.
