Metabones ARRI PL to Nikon Z T CINE Speed Booster ULTRA 0.71x

Sharper corners, less distortion, reduced vignetting

New 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 and Super35 camcorder, such as Sony E-mount, Fuji X-mount cameras Sony FS7 MARKII, 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/Prime lenses regardless of exit pupil distance.

Features:

• Design for attaching full-frame PL Prime Lens to Nikon Z-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;
• Rubber gasket protects the Z-mount connection from dust and moisture;
• 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);
