Metabones ARRI PL to RF T CINE Speed Booster ULTRA 0.71x (EOS R) (MB_SPPL-EFR-BT1)

Metabones ARRI PL to RF T CINE Speed Booster ULTRA 0.71x (EOS R) (MB_SPPL-EFR-BT1)

Sharper corners, less distortion, reduced vignetting

Optical design: Advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.

Like the revolutionary original Metabones Speed Booster® announced in January 2013, the Speed Booster ULTRA has a magnification of 0.71x, and so it effectively reduces the crop factor of mirrorless cameras with DX-sized sensors(APS-C), such as Sony E-mount and Fuji X-mount cameras, from 1.5x to 1.07x.  However, the new ULTRA design makes very effective use of exotic materials at the furthest limit of glassmaking technology, and as a result is well corrected for use with virtually all full-frame SLR lenses regardless of exit pupil distance. Thus, the Speed Booster ULTRA performs extremely well with professional-grade f/2.8 zoom lenses such as the 24-70mm f/2.8 and 70-200mm f/2.8 zooms by Canon and Nikon to produce 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zooms, respectively.  Similarly, high-speed fixed focal length lenses such as a 50mm f/1.2 will be transformed into a 35.5mm f/0.9 lens with excellent contrast and resolution from the center all the way to the edges of the image.

• Design for attaching full-frame PL Prime Lens to Canon RF-mount cameras/camcorders ;
• Increase maximum aperture by 1 stop;
• Increase MTF;
• Makes lens 0.71x wider;
• The advanced 5-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;
• Felt material flocked inside the opening to reduce internal reflection;
• Satin Surface Finish;
• Aluminum Alloy and Brass Construction with Chromium Plating;
• Detachable Arca-Type tripod foot compatible with Arca Swiss, Markins, and Photo Clam ball heads(clamp directly or attach to quick release plate by a 1/4"-20 screw);

Limitations
• Metabones PL T CINE Speed Booster® adapters are designed exclusively for the Zeiss CP.2, CZ.2, and CP.3 lenses.
Important Notes: Do not attempt to mount the lenses not under the Lens Comparability List to the adapter - physical damage may occur.
• Using the PL lens OTHER THAN the CP.2/ CP.3 lens, the lens's rear element CANNOT protrude from the flange more than 14.5mm. (note.1)
• This product is designed for the APS-C format camera (eg. Canon EOS C70, R7, R10, R50 and RED Komodo, etc.) or using the APS-Crop mode of EOS R3, EOS R5, EOS R6, EOS R and EOS RP.

Note:
(1) The Metabones PL T CINE Speed Booster adapters are designed exclusively for the Zeiss CP.2, CZ.2, and CP.3 lenses. If using the PL lens other than the CP.2/ CP.3 lens listed in the compatibility list, the lens's rear element CANNOT protrude from the flange more than 14.5mm. Do not attempt to mount the lenses not under the Lens Comparability List / the protrusion of the lens which exceeds 14.5mm to the adapter - physical damage may occur.
