Nikon Z8 vs Canon EOS R5 Mark II: connectivity and tethering compared
Do-everything high-resolution bodies for weddings, events and sport. 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.

| CloudTether over USB | Supported by the protocol, not yet tested by us (same code as our verified Nikon body) | Verified by us |
| CloudTether over Wi-Fi | Supported by the camera, not yet tested by us | Verified (Canon) |
| Rated send | Yes — only shots you rate in camera | Yes — only shots you rate in camera |
| Camera setting for a USB tether | None — default USB mode | None — turn the camera's Wi-Fi off before USB |
| Cable to a USB-C phone | USB-C to USB-C data cable | USB-C to USB-C data cable |
“Not stated” means the maker's spec page doesn't list it — we don't fill gaps with guesses. Wi-Fi bands can vary by region.
Verdict: which delivers faster?
Both have built-in FTP, 5 GHz Wi-Fi and dual slots. Canon lists the R5 Mark II's USB-C as SuperSpeed Plus (USB 3.2 Gen 2, 10 Gbps); Nikon lists the Z8's data port as SuperSpeed USB (the 5 Gbps tier). For a phone tether that gap rarely shows — most phones' ports set the limit — and Z8 users' transfers in our logs took a median 0.34 s per file over USB.
Both support rated send. The R5 Mark II is verified by us (USB in field use, Canon Wi-Fi verified); the Z8 shares its code with our verified Z6 but this exact body hasn't been tested, and Nikon Wi-Fi is untested. One Nikon quirk: an iPhone may not connect to a body with a CFexpress card until the card is formatted in the camera.
Pick the Z8 if…
…you're a Nikon shooter — the Z8 tethers in its default USB mode with nothing to set.
Pick the EOS R5 Mark II if…
…you want a verified body and a verified Wi-Fi tether for roaming without a cable.

Nikon Z8 vs Canon EOS R5 Mark II: FAQ
Which is faster to tether to a phone, the Z8 or the EOS R5 Mark II?
On paper the EOS R5 Mark II has the faster USB-C port (10 Gbps vs 5 Gbps per the makers' specs). To a phone the gap mostly disappears — standard USB-C iPhones and many Android phones run at USB 2 — and it shows mainly with big RAW files to a USB 3 device. A JPEG arrives in a fraction of a second either way.
Can both tether to a phone over Wi-Fi with CloudTether?
Z8: supported by the camera, not yet tested by us; EOS R5 Mark II: verified (canon). 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 and Canon tethering: switch on “Only shots I rate in camera” and only rated frames are sent.
Do the Z8 and EOS R5 Mark II have built-in FTP?
Z8: built-in (Connect to FTP Server); EOS R5 Mark II: built-in FTP transfer. 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.
