Nikon AF-S TC-14E III review: boost your telephoto powers

The Nikon AF-S TC-14E III gives a 1.4x boost in reach for compatible F-mount lenses but you’ll lose the usual f/stop along the way.

Digital Camera World Verdict

I’m sold on the Nikon AF-S TC-14E III. It gives a 1.4x magnification of focal length and maximum magnification factor for close-ups, with minimal degradation of image quality. And it’s a whole lot more cost-effective and easier to lug around than a hefty additional super-telephoto lens.

This is the 1.4x version of Nikon’s latest (and probably last) F-mount teleconverter, designed for Nikon cameras and compatible F-mount Nikon telephoto lenses. It’s primarily designed for DSLRs but can also be used on Z-mount mirrorless cameras via an FTZ or FTZ II mount adapter. As such, it’s one of the best teleconverters on the market. Typically for a 1.4x teleconverter, the focal length of the attached lens is magnified by a factor of 1.4x, with a 1 f/stop reduction in aperture rating, so a Nikon AF-S 70-200mm f/2.8E FL ED VR zoom effectively becomes a 98-280mm f/4 lens.

To avoid confusion, the specialist front cap is colored in a distinctive gray. (Image credit: Matthew Richards)

Nikon AF-S TC-20E III

The Nikon AF-S TC-20E III gives 2x magnification rather than 1.4x, so it’s more powerful but bigger and heavier, and you lose two f/stops in aperture instead of just one.
