Camera settings for tethering the EOS R5 Mark II
No USB mode to set on EOS bodies. Turn the camera's Wi-Fi off, make sure it isn't in a webcam or streaming mode, and plug in.
Use a data cable: USB-C to USB-C for a USB-C iPhone or Android phone, or Apple's Lightning to USB 3 Camera Adapter for a Lightning iPhone. On Android, accept the USB permission prompt.
MENU → Network settings → set Network to Enable, then set up the EOS Utility (remote control) connection — not the smartphone connection — on the same network as the phone. Approve the pairing on the camera.
On location, put the camera on your phone's hotspot so the phone keeps mobile data for uploads. More in wireless camera tethering.
How to tether the Canon EOS R5 Mark II to your phone
- 1
Set up the EOS R5 Mark II
No USB mode to set on EOS bodies. Turn the camera's Wi-Fi off, make sure it isn't in a webcam or streaming mode, and plug in. Lengthen auto power-off so the camera stays awake while tethered.
- 2
Connect it to your phone
Open CloudTether, tap “Connect a camera” and plug a USB-C cable from the EOS R5 Mark II into your iPhone, iPad or Android phone (a Lightning iPhone needs Apple's camera adapter). For Wi-Fi instead: MENU → Network settings → set Network to Enable, then set up the EOS Utility (remote control) connection — not the smartphone connection — on the same network as the phone. Approve the pairing on the camera.
- 3
Choose where the shots go
The “Send its shots to…” sheet shows where the camera is sending. Keep shots on the phone, or add Dropbox, Google Drive, a client gallery or an FTP/SFTP server — a shoot can send to several at once. Take a test shot.

Shoot as normal
Every frame your EOS R5 Mark II captures is copied to the phone at full resolution — JPEG or CR3 RAW — and delivered while you keep shooting. Each photo uploads from the phone once and goes to every destination.
What to know about the EOS R5 Mark II
- The EOS R5 Mark II is the body we used to check rated send end to end: rate a frame on the camera and only rated shots leave it.
- It's also our USB-vs-Wi-Fi benchmark: the same JPEGs took a median 0.06 s over USB and 0.20 s over Wi-Fi in our app logs.
- Its RAW files are large, so for live galleries shoot RAW+JPEG and turn on JPEG only — the CR3 files stay on the card.
