AF-S TC-17E II Teleconverter

The Nikon AF-S Teleconverter TC-17E II is a 1.7x magnification converter designed for Nikon F-mount lenses that extends the effective focal length of compatible AF-S NIKKOR lenses by 70 percent. This teleconverter maintains full autofocus, exposure metering, and vibration reduction capabilities while introducing only a 1.5-stop loss of light, making it a practical solution for extending lens reach. The optical design consists of seven elements in four groups with Nikon's Integrated Coating to minimize flaring and ghosting.

The TC-17E II supports both FX and DX format AF-S NIKKOR lenses and weighs 8.8 ounces, making it compact and portable for field use. Full compatibility details are available on the Nikon USA website, as certain lens and camera combinations may have specific requirements for optimal performance.
