Metabones Canon EF to Sony E-Mount T Speed Booster ULTRA II 0.71x (Fifth Generation)

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.

Features:

  • Adapt a full-frame Canon EF-Mount lens to an APS-C/Super35 Sony E-Mount camera, or a full-frame camera in APS-C mode.
  • Advanced 5-element in 4-group optical construction uses ultra-high index tantalum-based glass.
  • Increases angle of view of a full-frame lens by 0.71x and the max aperture by one stop.
  • Electronic contacts permit transmission of data between certain lenses and cameras to enable autofocus, auto exposure, and more.
  • Status notification LED light on the adapter will show the user what mode the adapter is currently in.
  • Dedicated switch for controlling in-body image stabilization.
  • Programmable function button for rapid access to commonly used settings and features.
  • Support for phase-detect AF with the A7R II, a7 II, a6500, and a6300 cameras.
  • Internal felt flocking prevents reflections.
  • Removable Arca-type compatible tripod foot with 1/4"-20 thread.
