Metabones PL to Emount T CINE Speed Booster ULTRA 0.71x (Black Matt)

Product Description A new optical design with five elements in four groups of tantal-based optical glass with a very high refractive index, provides exceptional optical performance with improved sharpness in the corners, low distortion and reduced vignetting. As the original Metabones Speed booster introduced in January 2013, the Speed Booster Ultra also has a 0.71x magnification and thus effectively reduces the crop factor of mirrorless cameras with DX sized sensors such as Sony E-mount and Fuji X-Mount from 1, 5 to 1, 07. The new ultra design and the effective use of selected materials in glass production ensures that the Speedbooster Ultra can be used practically with all full-frame lenses, regardless of the distance of the exit pupil.
