Tamron SP 1.4X Pro Teleconverter for Canon EOS

( Focal Length: 420mm - Lens Aperture: 4f-stops )

The Tamron SP AF Pro teleconverter features improved optical construction, and is designed to be used with lenses that are f/2.8 and of focal lengths of 90mm or greater.The 1.4x teleconverter (also known as a tele-extender) will multiply the focal length of the existing lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300mm lens will effectively increase the focal length to 420mm. A lens set to f/2.8 will now be f/4.Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above.&ref=Become
