Metabones SPEF-M43-BTB – Canon EF to Blackmagic Pocket Cinema Camera 4K CINE Speed Booster XL 0.64x

Metabones SPEF-M43-BTB – Canon EF to Blackmagic Pocket Cinema Camera 4K CINE Speed Booster XL 0.64x

This Speed Booster version is redesigned for the 2.4 mm filter stack of Blackmagic cameras rather than the 4 mm of standard Micro Four Thirds, and is dedicated to the Pocket Cinema Camera 4K. It reduces the BMPCC4K crop factor from 2.02x to 1.29x and makes the lens 1 1/3 stops faster, up to f/0.80. Metabones recommends the XL for full-frame lenses and the ULTRA for APS-C lenses.

Features

• 0.64x magnification and 1 1/3 stops more maximum aperture (up to f/0.80)
• Patented 7-element/4-group optical design by Caldwell Photographic (USA)
• Aperture set from the camera, with smooth iris on Canon (2009+), Tamron SP (2013+) and Sigma (2016+) lenses
• IS lens support and push autofocus where the camera supports it; powered by the camera with most lenses
• Patented positive-lock CINE EF mount, no play while focusing
• Detachable Arca-type tripod foot matched to the BMPCC4K body height, with 1/4"-20 thread
• Rubber gasket on the mount, aluminium and chrome-plated brass, flocked interior

Note: It cannot be fitted to JVC, Olympus or Panasonic Micro Four Thirds cameras. The image circle does not cover a full-frame sensor; in rare cases external 5 V power via micro USB is needed (not included).
