Description — Nikon TC-17E II
The Nikon AF-S Teleconverter TC-17E II is built for Nikon F mount DSLR systems and carries a full-frame format designation, making it compatible with the full range of Nikon's full-frame and crop-sensor DSLR bodies. It sits in the telephoto focal length category, reflecting its role as a companion to longer telephoto lenses where additional reach is the goal. A key practical advantage is its autofocus support — AF capability is preserved when the teleconverter is paired with a compatible Nikon F mount lens, keeping fast-response shooting workflows viable.
Weighing in at 250g, the TC-17E II is a relatively compact addition to a telephoto kit. There is no filter thread, and image stabilization is listed as none, meaning any stabilization depends on the host lens. For photographers working within the Nikon F mount DSLR ecosystem who need extended telephoto reach without sacrificing autofocus, the TC-17E II is a direct, mount-native solution.
