FAQ:

Q: What lens mounts can you use a speed booster with?

A: For example, you can get a Speed Booster for mounting Canon EF lenses, Nikon lenses, and even for shooting with vintage lenses such as Canon FD. Which Lens Mount is Best?

Q: How does the speed booster affect aperture?

A: A lens’ aperture is relative to its focal length, so it is similarly affected by the focal reduction factor of the Speed Booster’s optics. The Speed Booster’s optics concentrate more light on to the sensor, giving you a brighter image.

Q: What does the speed booster ultra do?

A: The Speed Booster’s optics concentrate more light on to the sensor, giving you a brighter image. For example, a lens with a f/1.4 maximum aperture has a f/1.0 maximum aperture with the Speed Booster Ultra, effectively increasing the lens’ aperture by 1 full stop.

Q: What is the focal reduction factor of the speed booster ultra?

A: For example, the Speed Booster Ultra has a 0.71x focal reduction factor, which means a 50mm lens has a focal length of 35.5mm (rounded to 36mm) when used with this adapter. A lens’ aperture is relative to its focal length, so it is similarly affected by the focal reduction factor of the Speed Booster’s optics.
