Metabones FD to Fuji X-mount Speed Booster ULTRA 0.71x (MB_SPFD-X-BM3)
Optical Performance
The Speed Booster ULTRA features an advanced 5-element/4-group optical design incorporating ultra-high index tantalum-based optical glass, developed by Caldwell Photographic in the USA. This design delivers extraordinary optical performance with sharper corners, less distortion, and reduced vignetting.
With a magnification factor of 0.71x, it effectively reduces the crop factor of mirrorless cameras with APS-C sensors, such as Fuji X-mount and Sony E-mount cameras, from 1.5x to approximately 1.07x. The ULTRA design utilizes exotic materials at the forefront of glassmaking technology, ensuring excellent correction for virtually all full-frame SLR lenses regardless of exit pupil distance.
Lens Compatibility and Aperture Enhancement
The Speed Booster ULTRA performs exceptionally well with professional-grade f/2.8 zoom lenses like Canon and Nikon 24-70mm f/2.8 and 70-200mm f/2.8 zooms, effectively transforming them into 17-50mm f/2.0 and 50-142mm f/2.0 high-speed zoom lenses, respectively. High-speed prime lenses, such as a 50mm f/1.2, are converted into a 35.5mm f/0.9 lens, maintaining excellent contrast and resolution from the center to the edges of the image.
