Nikon Z6 III vs Nikon Z6 II: connectivity and tethering compared

Z6 II owners deciding whether the Z6 III is worth it for delivering as they shoot. This comparison is about one thing: how fast each body gets a finished frame to where it's needed — its USB-C port, Wi-Fi, built-in FTP, Ethernet and card slots, and how it tethers to a phone with CloudTether.

Verdict: which delivers faster?

For tethering to a phone over USB they're the same: both have a SuperSpeed USB-C port, both tether in Nikon's default USB mode, and both run the same CloudTether code as our verified Nikon Z6 — with rated send available on either.

The upgrade is networking. The Z6 III has Connect to FTP Server in its own Network menu (over Wi-Fi, or Ethernet through a USB-C adapter) and the Wi-Fi connection (STA mode) route CloudTether's wireless pairing uses. The Z6 II's manual has no FTP section — networking goes through Nikon's optional WT-7 transmitter — and its wireless tethering in CloudTether is untested.

Pick the Z6 III if…

…you want in-camera FTP as a second delivery path, or to try a Wi-Fi tether.

Pick the Z6 II if…

…you tether over USB anyway — the Z6 II delivers through CloudTether exactly the same way.

Nikon Z6 III vs Nikon Z6 II: FAQ

Which is faster to tether to a phone, the Z6 III or the Z6 II?

Their USB-C ports are the same class on paper (5 Gbps per the makers' specs). To a phone, the phone's own port usually sets the limit — standard USB-C iPhones and many Android phones run at USB 2 — and a JPEG still arrives in a fraction of a second (a median 0.06 s from an EOS R5 Mark II in our logs).

Can both tether to a phone over Wi-Fi with CloudTether?

Z6 III: supported by the camera, not yet tested by us; Z6 II: supported by the camera, not yet tested by us. Canon Wi-Fi is the wireless tether we've verified; USB is the dependable path on every body.

Which one can send only the shots I rate?

Both. Rated send works over Nikon tethering: switch on “Only shots I rate in camera” and only rated frames are sent.

Do the Z6 III and Z6 II have built-in FTP?

Z6 III: built-in (Connect to FTP Server); Z6 II: not in the camera's own menus — networking goes through Nikon's optional WT-7 transmitter. In-camera FTP is a separate path from a phone tether — CloudTether can also deliver to an FTP/SFTP server from the phone, on any body.
