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 E mount and 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.
