Description — Nikon TC-20E III
The Nikon AF-S TC-20E III Teleconverter is a Nikon F mount telephoto accessory built for DSLR camera systems. Designed to cover the full frame format, it integrates seamlessly with Nikon F mount lenses and bodies without introducing coverage limitations on full frame sensors. The teleconverter operates as a prime optical element and supports Auto and Manual focus modes, giving photographers the ability to use autofocus when paired with compatible lenses or switch to manual when precision is required.
With a weight of 330g, it adds a manageable amount of mass to a telephoto setup. Image stabilization is not present in the unit itself, so shooters should rely on any stabilization available in their lens or camera body. There is no filter thread on the unit, and no hotshoe connection.
For Nikon DSLR photographers already invested in the F mount ecosystem, the TC-20E III offers a native-mount teleconverter option that preserves autofocus functionality.
