The Nikon TC-14E II Teleconverter has been updated to match
with AF-S type lenses, and will maintain full metering and focusing with
compatible cameras and lenses. This converter will increase the focal
length of the lens by 1.4x, and reduces the lens aperture by one f-stop.
Note! Autofocusing only possible when used with D1, D1X, D1H, D100, F5, F100, N90s, N80, N75, N65 AF SLR cameras, and any newer models.
