FAQ:

Q: What is the Canon EF speed booster?

A: The EF Speed Booster is an active adapter, which means it contains electronics that allow the camera to communicate with electronically-controlled Canon EF-mount lenses. There are already a bunch of inexpensive passive Canon EF lens adapters, but only an active adapter provides essential lens functionality such as aperture control.

Q: What are the best lenses for the Canon EOS 7D speed booster?

A: The Tokina 11-16mm f/2.8 is an interesting lens for use with the Speed Booster. When paired with the Speed Booster, this lens’ FOV matches a 7.8-11.4mm lens.

Q: What lenses are compatible with the EF speed booster?

A: The EF Speed Booster is compatible with both full frame and APS-C EF lenses, providing you with a vast array of lenses to choose from. Note: Canon EF-S mount lenses are not compatible with the EF Speed Booster because the mount extends further out and comes into contact with the Speed Booster’s optics.

Q: What is a speed booster and how does it work?

A: A speed booster is a converter that reduces both the aperture and the focal length of the attached lens, therefore ‘boosting the speed’ of your lenses. In the latest Japanese patent (2018-189864) uncovered by Canon News, Canon cites a 50mm f/1.4 lens converting to a 40mm f/1.2 on the EOS M system.
