Metabones Released PL to Sony E-mount T CINE Speed Booster ULTRA 0.71x

By on

Metabones has released a new PL to Sony E-mount T CINE Speed Booster ULTRA 0.71x.

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 like A7 series or NEX-VG900, the camera needs to have “APS-C/Super 35mm” set to either “Auto” or “On”.

Only support full-frame PL Prime lenses, e.g. Compact Prime CP.2 Lenses. Super 35 PL Prime lenses are NOT supported.

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 fullframe SLR/Prime lenses regardless of exit pupil distance.
