Digital Camera World Verdict

Compatible with a wide range of Nikon Z-system telephoto prime and zoom lenses, this teleconverter delivers a 1.4x magnification in overall focal length. It’s beautifully engineered with a weather-sealed, anodized aluminum casing and high-quality glass, complete with coatings. Performance is exemplary and, while it’s pretty pricey for a 1.4x teleconverter, it’s worth every cent when your telephoto lens comes up short and won’t cover the distance.

The Nikon Z Teleconverter TC-1.4x aims to bury a bad reputation. Historically, teleconverters have been somewhat notorious for degrading image quality and all-round performance. It’s literally like holding a magnifying glass to the image circle produced by a lens, and accentuating every slight flaw in its optical performance. The speed and accuracy of autofocus can also take a hit. However, as we reported previously, Nikon says its Z-mount teleconverters will not degrade image quality. The company also says you’ll ‘enjoy the focusing speed you’ve come to expect from Nikon Z’. As promised, we’ve now put those claims to the test, for the TC-1.4x as well as the TC-2.0x, the latter reviewed separately.
