Metabones Rollei QBM Lens To Fujifilm X-Mount Camera Speed Booster ULT
Sharper corners less distortion reduced vignetting New optical design:Advanced 5-element/4-group optical design incorporating ultra-high index tanatalum-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 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 fullframe 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.
