DETAILS
The Tamron 1.4x teleconverter will multipy the focal length of your lens by 1.4x. This teleconverter also cuts light access by one f/stop. This teleconverter is not recommended for lenses that are wider than 50mm, and Autofocus will only work properly with open aperture that is f/2.8 or brither. With lenses that have smaller open f/stop values it is recommended to use manual focusing.
