Metabones ARRI PL Lens to Canon RF-Mount T Cine Speed Booster ULTRA 0.71x (EOS-R)

Arri PL Lens to BMPCC4K T Cine Speed Booster Ultra 0.71x

Always Enhance and Never Degrade the Performance of the Attached Master Lens

Like the ULTRA series for Mirco Four-Thrids mount, the new BMPCC4K Speed Booster​® ULTRA 0.71x uses an advanced 6-element 4-group optical design incorporating ultra-high index tantalum-based optical glass.  However, the new design is specifically optimized for the BMPCC4K sensor and filter stack, and as a result, achieves an astonishing level of performance that sets a new standard for focal reducers.

Key Features:

• Design for attaching PL Prime Lens to Blackmagic M43-mount cameras/camcorders
• Increase maximum aperture by 1 stop
• Increase MTF
• Makes lens 0.71x wider
• The advanced 6-element/4-group optical design incorporating ultra-high index tantalum-based optical glass by Caldwell Photographic in the USA (patent granted)
• Positive-lock PL lens mount
• Flocking to reduce internal reflection
• Aluminum alloy and brass construction with chromium plating
• Satin surface finish
• Detachable tripod foot compatible with Arca Swiss Style ball head, such as Markins and Photo Clam or attach to quick release plate by a 1/4"-20 screw
• The tripod foot is tailor-made to match the exact height as the BMPCC4K camera body

Metabones ARRI PL to BMPCC4K Speed Booster adapters is designed exclusively for Blackmagic Design Pocket Cinema Camera 4K (BMPCC4K). They cannot be attached to any other M43 cameras such as JVC, Olympus or Panasonic cameras. The BMPCC4K Speed Booster ULTRA 0.71x reduces the crop factor of the BMPCC 4K camera from 2.02x to 1.43x and produces the largest aperture optics currently available, with a maximum output aperture of f/0.9.
