The Canon EF Lens to Sony NEX Metabones Speed Booster is an electronic adapter that allows you to pair Canon EF mount lenses with crop frame sensor Sony E mount cameras. It 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 wider or, in other terms, reducing the crop factor of the camera from 1.5x to 1.07x – nearly full frame. For example, a 40mm 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. 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.

Special Notes:

  • • 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 camera, please make sure "APS-C/Super 35mm" is set to either "Auto" or "On".
  • • 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.
  • • Partial Autofocus is supported in post-2006 Canon EF mount lenses. Autofocus speed is very slow and inadequate for most moving subjects.
  • • 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 Sony NEX-VG900 is not compatible with this adapter.
