Description

The new Version III 2x Extender is optically redesigned for better sharpness and less “color fringing”, is stronger and more durable, and offer even better AF accuracy.

Two stop effective light loss: AF with all EOS bodies when attached to lens f/2.8 or faster; with 45-point AF cameras, AF at center point (only) when used with f/4 lenses.

The 2x extender (also known as a teleconverter) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6. Teleconverters are best used with longer telephoto lenses and are not recommended for lenses wider than 50mm, e.g. 28-105mm (35mm format).

Note: This teleconverter will only fit and work with a select list of lenses. Please click here for a compatibility chart of all compatible lenses.
