    Nikon AF-S Teleconverter TC-20E II

    Overview

    The Nikon AF-S Teleconverter TC-20E II is a 2x teleconverter that doubles focal length while reducing aperture by two stops. It maintains full metering and AF with compatible AF-I/AF-S lenses. Optically, it causes some loss of sharpness and contrast wide-open. Build quality is typical Nikon pro-grade, though it only fits AF-I/AF-S lenses without modification. It suits users needing extreme reach with high-end Nikon lenses, but those prioritizing sharpness may prefer the TC-17E.
