AF-S TC-20E II Teleconverter

The Nikon TC-20E II is a 2x teleconverter designed for use with AF-S and AF-I Nikon lenses, effectively doubling the focal length of compatible optics while reducing the aperture by two f-stops. This teleconverter features full autofocus and metering compatibility with newer Nikon camera bodies and select compatible lenses, maintaining the optical quality needed for professional telephoto work. The unit is constructed with seven lens elements arranged in six groups and weighs just 12.5 ounces, making it a lightweight addition to any telephoto lens setup.

Compatibility is limited to specific Nikon lens models as detailed in the manufacturer's compatibility list, with some longer focal length lenses experiencing autofocus limitations when the teleconverter is attached. The TC-20E II works across FX and DX formats and is fully compatible with 35mm film cameras, providing versatility across multiple camera systems and sensor types.
