Overview

The Nikon AF-S Teleconverter TC-14E II is a 1.4x converter that loses one stop of light and adds 40% focal length. Optically, it delivers sharp results across compatible AF-S and AF-I telephoto lenses, with minimal sharpness penalty. Build is identical to the original TC-14E except for cosmetics; the front element protrudes and is shrouded in rubber that may develop haze over time. It only works with specific AF-S/AF-I lenses and may degrade autofocus on slower lenses. Best suited for users with high-quality Nikon telephoto lenses seeking a modest reach extension.
