Metabones SPEF-M43-BT8 – Canon EF to Blackmagic Pocket Cinema Camera 4K T Speed Booster ULTRA 0.71x

Metabones SPEF-M43-BT8 – Canon EF to Blackmagic Pocket Cinema Camera 4K T Speed Booster ULTRA 0.71x

Speed Booster designed for the Blackmagic Pocket Cinema Camera 4K: the optics are redesigned for the 2.4 mm filter stack of Blackmagic cameras instead of the 4 mm of standard Micro Four Thirds. With Canon EF lenses it reduces the crop from 2.02x to 1.43x, with a maximum output aperture of f/0.9.

Features

• Patented 6-element/4-group optical design by Caldwell Photographic (USA), optimised for the 2.4 mm sensor filter stack of Blackmagic cameras
• Increases the maximum aperture of the lens by 1 stop, up to f/0.9 output
• Increases the MTF of the attached lens
• Makes the lens 0.71x wider
• Reduces the crop factor of the Pocket Cinema Camera 4K from 2.02x to 1.43x
• Lens aperture set from the camera controls
• Smooth iris with recent Canon (2009+), Tamron SP (2013+) and Sigma (2016+) lenses
• Image stabilisation (IS) lens support
• Push autofocus if supported by the camera
• Cinema EOS lens support (CN-E 18-80mm T4.4 L) with autofocus (requires external 5V power via micro USB), auto iris and servo zoom
• Powered by the camera body: no external power needed with most lenses
• Felt-flocked interior to reduce internal reflections
• Rubber gasket protects the MFT connection from dust and moisture
• Aluminium alloy and brass construction with chrome plating
• Satin surface finish
• Detachable Arca-type tripod foot (direct clamp or 1/4"-20 screw), tailor-made to match the height of the Pocket Cinema Camera 4K body

Note: It fits only Blackmagic Design cameras with MFT mount: it cannot be attached to JVC, Olympus or Panasonic Micro Four Thirds cameras. Compatible cameras: Blackmagic Pocket Cinema Camera 4K, Pocket Cinema Camera HD (original version), Micro Cinema Camera, Micro Studio Camera 4K and 4K G2, Studio Camera 4K Plus G2, Studio Camera 4K Pro G2, Studio Camera 4K and Studio Camera. It covers the Pocket Cinema Camera 4K image circle, not a 36 x 24 mm sensor. Canon EF-S lenses need modification or may remain incompatible, and EF Extender 1.4x and 2x teleconverters do not fit. Metabones recommends the XL 0.64x version for full-frame lenses and the ULTRA for APS-C/DX lenses.
