Metabones T Speed Booster ULTRA 0.71x Adapter for Canon EF Lens to BMPCC 4K Camera

The Metabones T Speed Booster ULTRA 0.71x Adapter for Canon EF Lens to BMPCC 4K lets you mount a full-frame Canon EF lens to a Blackmagic Design Pocket Cinema Camera 4k, Micro Cinema Camera 4K, and Blackmagic Studio Camera. The adapter's optics aid to maximize the attached lens' apparent angle of view while also giving the camera a 1-stop increase over the lens's aperture range. This 0.71x converter supports auto iris and servo zoom on Cinema EOS lenses, as well as AF (autofocus) via the micro-USB interface, which requires external 5V power.
