Metabones SPEF-M43-BT9 – Canon EF to Blackmagic Pocket Cinema Camera 4K 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
