Description
Metabones® Speed Booster® ULTRA 0.71x for E-Mount and X-mount cameras
Always Enhance and Never Degrade the Performance of the Attached Master Lens.
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.
