The new TC-20E II has now been updated to match with the new AF-S lenses, and will maintain full metering and focusing with compatible cameras and lenses. This converter will increase the focal length of the lens by 2x (100%), and reduces the lens aperture by two f/stops.
Due to the high-quality design of this converter (7 elements/6 groups), the teleconverter will only fit and work with a select range of lenses, but with limitations. Only the following lenses are compatible:
AF-S 70-200mm f/2.8G ED-IF VR
AF-S 80-200mm f/2.8D ED-IF
AF-S 200-400mm f/4G ED-IF VR (manual focus only)
AF-S 105mm f/2.8G ED-IF VR (manual focus only)
AF-S 200mm f/2G ED-IF VR
AF-S 300mm f/2.8D ED-IF (II)
AF-S 300mm f/4D ED-IF
AF-S 400mm f/2.8D ED-IF (II)
AF-S 500mm f/4D ED-IF (II)
AF-S 600mm f/4D ED-IF (II)
Autofocusing only possible when used with D1, D1X, D1H, D100, F5, F100, N90s, N80, N75 and N65 AF SLR cameras, or any newer models.
Only limited AF with AF-S 500mm f/4D ED-IF (II) and AF-S 600mm f/4D ED-IF (II).
