Tamron Standard Teleconverters
The 1.4X teleconverter will increase the focal length of the master lens by 1.4X and make the lens one f-stop slower.. Though using a teleconverter on wide-angle lenses is never really recommended, these converters can be used with lenses that are wider than 90mm and are ideal for all lenses that are not F/2.8's.
The 1.4X teleconverter can be used with both AF and MF lenses. AF will be retained if the master lens is F/4.5 or faster.
Not compatible with the Nikon D40, D40x or D60. |
