The Nikon Z 70‑200mm f/2.8 VR S II is the latest generation of Nikon's professional telephoto zoom, designed for high-performance stills and video work – it's one of Nikon's most advanced telephotos to date.
While the lens is widely regarded as a strong option in its class for sports, wildlife, and event photography, photographers noticed that the autofocus (AF) response slowed down when the telephoto was used with the Nikon Z Teleconverter TC-2.0x.
