Key Features

Speed Booster ULTRA  for E-Mount and X-mount cameras

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 camcoder, 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.

Limitations

Optical/mechanical
 
    •    Metabones PL T CINE Speed Booster TM 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.
    •    Speed Booster ULTRA is designed to cover an APS-C/Super35 image circle which is not big enough to cover a full-size 36mm x 24mm sensor. On a full frame camera body (A7 series, NEX-VG900) the camera needs to have "APS-C/Super 35mm" set to either "Auto" or "On".
