Does the Nikon NIKKOR Z 100-400mm f/4.5-5.6 VR S take a teleconverter?

Nikon Z · 100-400mm f/4.5-5.6 · thread and mount data verified 2026-08-29

2 teleconverters are supported. A teleconverter multiplies the focal length and costs you light — and on a crop body the framing multiplies again.

Both converters are supported and both stay usable: 140-560mm at f/6.3-8 with the 1.4x, 200-800mm at f/9-11 with the 2x. On a lens this fast the 2x is the unusual case of a 2x that does not cost you autofocus.

Nikon Z Teleconverter TC-2.0xYes — Nikon officially lists this pairing with AF/VR retained and states NO restriction; the 'partial' downgrade was based purely on a reviewer's subjective opinion, which would have fabricated an official limitation that does not exist. Independent commentary, clearly non-manufacturer: DPReview notes the 2x 'might be pushing it' at the resulting f/9-11, and low-contrast AF suffers. Present that as third-party commentary, never as a Nikon restriction.200-800mmf/9-11300-1200mm

At f/9-11 some older bodies restrict autofocus to the centre point.

Compatibility sourced from the manufacturers' own published teleconverter compatibility statements (manufacturer teleconverter compatibility statements (Sony, Canon USA, Nikon, Fujifilm, Sigma, Panasonic, OM System) — each row carries its own source URL) and verified 2026-08-29. Reach and aperture figures are computed from the lens's own published focal length and maximum aperture — a 1.4x multiplies focal length by 1.4 and costs 1 stop; a 2x multiplies by 2 and costs 2 stops. Lenses whose compatibility we could not verify from a manufacturer statement are omitted rather than guessed. Methodology
