The Fotodiox 2x Teleconverter for Canon cameras is a precisionoptical component designed to expand your photographiccapabilities. This premium quality 2x teleconverter, effectivelydoubles the focal length of the lens it's used with andmaintains the resolution and contrast of any fine optic.
The teleconverter will multiply the focal length of the existinglens by 2x, and will cut back the amount of light by 2 f/stops. Forexample, using a 2x teleconverter with a 300 mm lens willeffectively increase the focal length to 600 mm and a lens set tof/2.8 will now be f/5.6.
A maximum aperture of f/4 or greater is required in order tofully utilize the autofocus capabilities. Please be aware that AFwill work properly only if there is enough light and contrast onthe subject to activate the camera's AF sensors. Manualfocusing is recommended when using lenses with a smaller openf-stop value than those given above.
A teleconverter is a portable, high-quality and versatileaccessory that's well worth having in your camera bag!
