Does the Nikon NIKKOR Z 100-400mm f/4.5-5.6 VR S take a teleconverter?
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.
| Teleconverter | Supported | Reach | Max aperture | On APS-C | On Micro Four Thirds |
|---|---|---|---|---|---|
| Nikon Z Teleconverter TC-1.4x | Yes — Effective aperture ~f/8 at the long end; generic Nikon AF caveat applies. | 140-560mm | f/6.3-8 | 210-840mm | — |
| Nikon Z Teleconverter TC-2.0x | Yes — 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. | 200-800mm | f/9-11 | 300-1200mm | — |

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
