Reductor-Focal Ultra Metabones de Leica-R a Sony montura-E (MB_SPLR-E-BM2)

Speed Booster ULTRA

Mayor nitidez en las esquinas, menor distorción, viñeteado reducido

Nuevo diseño óptico: Diseño avanzado de 5 elementos/ 4 grupos incorporando cristal de índice ultra-alto de base de Tántalo para conseguir un rendimiento óptico con nitidez mejorada en las esquinas, menosr distorsión y viñetado reducido.

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.
