The Metabones Canon EF Lens to Sony E Mount Camera T Cine Speed Booster ULTRA is a cinema-styled electronic adapter that allows you to pair Canon EF mount lenses with Sony E/FE mount cameras and increases the effective field of view and the maximum aperture of the lens you're using. This combats the crop factor of your APS-C camera while allowing you to use your favorite Canon EF mount lenses.

This Speed Booster works by shrinking the image circle of your Canon EF lens down to better fit APS-C 1.5x crop sensors. This has the effect of making the field of view of the lens 0.71x wider or, in other terms, reducing the crop factor of the camera from 1.5x to 1.07x – nearly full frame. For example, your Canon 40mm f/2.8 STM lens becomes an effective 42.8mm with this Speed Booster on an APS-C sensor instead of the 60mm effective view you'd have with a straight adapter. Additionally, by concentrating the image circle from a lens, this Speed Booster also "brightens" the image – maximum lens apertures are increased by approximately 1 stop down to the sub-f/1.0 range. Lastly, the Metabones Canon EF Lens to Sony E Mount Camera T Cine Speed Booster ULTRA supports Smooth Iris functionality in certain lenses (see the Notes tab for more). This adapter is ideal for those who want to use their full frame Canon lens collection on Sony E mount cameras that have either APS-C sensors, Super 35 sensors, or ASP-C/Super 35 modes without sacrificing angle of view.

  • • This Speed Booster is compatible only with EF mount lenses and not Canon EF-S mount lenses.
  • • This Speed Booster is designed for cameras with APS-C sensors. If you are using a full frame E mount (FE) camera, please make sure "APS-C/Super 35mm" is set to either "Auto" or "On".
  • • This Speed Booster will not operate correctly when trying to use it on Canon's CN-E collection of cinema lenses for still photography purposes.
  • • The first two AF attempts are used to calibrate the lens. Half-press the shutter release button again after that and AF will lock successfully.
  • • While technically compatible with any EF mount lens, please take notice if your third-party lens has any mount protrusions, like spikes or levers. These will damage the Speed Booster.
  • • Autofocus is supported with this Speed Booster but with certain contrast/phase detection limitations. Please see the notes below about lens compatibility.
  • • If you are attempting to pair both a Canon lens with a Canon extender to this Speed Booster, autofocus is disabled if the combined maximum aperture of the lens and the extender is f/5.6 or smaller (higher number).
  • • Use of this Speed Booster with a body using an aftermarket battery grip may result in strange aperture changes. Turn off the battery grip if you experience this. Behavior is not found when using Sony-branded grips.
  • • The following E mount camera bodies have been tested by Metabones for use with this Speed Booster:

  • Sony a9
  • Sony a7S, a7S II
  • Sony a7R, a7R II
  • Sony a7, a7 II
