Note:

  • Requires lenses supporting distance information.
  • Autofocus disabled for Contax N and Contax 645 lenses.
  • A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
  • This Speed Booster™ is designed to cover an APS-C image circle which is not big enough to cover a full-size 36mm x 24mm sensor.
  • Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with the Speed Booster™, the resulting aperture is f/0.9 but the camera body displays f/1.0.
