Overview
The Metabones Canon FD to Fuji X Speed Booster ULTRA 0.71x features an 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 original Metabones Speed Booster, the Speed Booster ULTRA has a magnification of 0.71x, effectively reducing the crop factor of mirrorless cameras with DX-sized sensors (e.g., Sony E-mount and Fuji X-mount cameras) from 1.5x to 1.07x. 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 lenses, regardless of exit pupil distance.
Subsequently, 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.
