Capture One not detecting your camera? Tethering fixes
Short answer: if Capture One won't see your camera, check that the model is on Capture One's supported list for tethering in your version, quit every other app that can hold the camera (Lightroom, the maker's utility, Photos or Image Capture), set the camera's USB mode — PC Remote on Sony, USB tether shooting on Fujifilm — and turn its Wi-Fi off, then connect with a known data cable straight into the computer. Those cover most cases; the eight fixes below go in the order we'd try them.
How Capture One shows a tethered camera
In Capture One Pro on Mac or Windows, tethering lives in the Capture tool tab. When a supported camera is connected, the Camera tool shows its name, battery and exposure settings, with a capture button and, on supported bodies, Live View. If it says no camera is attached, Capture One can't talk to the body yet. Setting up a tethered session from scratch is covered in our Capture One tethering guide; this page is for when it doesn't work.
Eight fixes, in order
Disconnect the camera before each change and reconnect after, so you know which fix did it.
Check tethering support for your model and version
Capture One lists supported cameras with a separate note on tethering, and some bodies are supported for RAW editing but not tethering, or only from a certain version. Check your exact model, your Capture One version and your operating system.
Update Capture One and the camera firmware
Support for newer bodies and tethering fixes arrive in updates. Update the camera's firmware too, especially if it's a recent release.
Quit everything else that can hold the camera
Only one program can control a camera at a time. Quit Lightroom Classic's tethered capture, Canon EOS Utility, Nikon NX Tether, Sony Imaging Edge, the Fujifilm Tether App, webcam utilities and photo-import tools. On a Mac, close Photos and Image Capture; on Windows, dismiss the import prompt.
Set the camera up for tethering
Turn the camera's Wi-Fi and Bluetooth connection functions off. Sony: USB Connection set to PC Remote (Remote Shooting on newer menus). Fujifilm: USB tether shooting (auto or fixed) in the connection settings. Older Nikon bodies that mount as a drive: choose MTP/PTP. Canon: usually nothing to set. Disable auto power off and keep a card in the camera.
Swap the cable and plug in directly
Use a data cable you trust, straight into a port on the computer rather than a hub or monitor. Try another port. For long runs, use an active cable rather than a long passive one or a chain of extensions.
Check the capture folder
In the Capture tool tab, check Next Capture Location points at a folder that exists, on a drive that's connected and has space. If Capture One can't write the file, the shot never appears.
Allow the connection in the operating system
On recent Mac laptops with Apple silicon, allow the USB accessory when macOS asks, or check Privacy & Security › Allow accessories to connect. Allow access to removable volumes if your session is on an external drive. On Windows, check the camera shows up in File Explorer or Device Manager.
Restart in a clean order
Quit Capture One, switch the camera off and unplug it. Open Capture One, plug the camera in, then switch it on. If something is still holding the camera, restarting the computer releases it.
Sony, Fujifilm, Canon and Nikon specifics
Sony is the commonest support question: the camera must be in PC Remote, and on many bodies there's a save destination setting (PC only, PC+Camera, camera only) that decides whether files reach the computer at all. Fujifilm bodies need the USB tether shooting mode; a plain USB card reader or webcam mode won't tether. Canon bodies with wireless on often refuse USB until Wi-Fi is turned off. Nikon Z bodies tether as they come, but a camera left in a network or wireless transmitter mode may need switching back to USB.
Detected, but images don't arrive
If the camera appears but frames don't land, check the camera's own save destination (Sony), that the capture folder is writable, that the camera isn't set to record to the card only, and that you aren't shooting video by mistake. Very large files over USB 2 can also arrive slowly enough to look like they're missing — wait a few seconds after the first frame before you assume it failed.
Wireless tethering in Capture One
Capture One supports wireless tethering on selected cameras, on desktop and on iPad. If a wireless connection won't appear, check your camera is on the wireless list, that the camera and computer are on the same network (not a guest network that isolates devices), and that any pairing prompt on the camera has been accepted. For a fixed studio set, a cable is faster and more predictable.
Workarounds while you sort it out
Let the camera maker's free utility tether to a folder and have Capture One pick the files up from it, using Capture One's hot-folder option — our glossary entry on hot folders explains the idea. You lose Capture One's own camera controls but keep the session moving. If the shoot is on location and what you actually need is every frame backed up and delivered, CloudTether tethers Canon, Nikon, Sony and Fujifilm to a phone and sends each shot to a shared folder as you shoot; it has live view and a remote shutter, but no exposure control.
FAQ
Why does Capture One say no camera attached?
Usually another app has the camera, the model isn't supported for tethering in your version, the USB mode is wrong (PC Remote on Sony, USB tether shooting on Fujifilm), the camera's Wi-Fi is on, or the cable doesn't carry data.
Why won't my Sony tether to Capture One?
Set USB Connection to PC Remote, check the save destination includes the PC, quit Imaging Edge and other apps, and update Capture One and the firmware.
Does Capture One tether Fujifilm cameras?
Yes, on the models Capture One lists, with the camera in its USB tether shooting mode.
Can Capture One and Lightroom tether at the same time?
No. Only one program can control the camera, so quit one before using the other.
Can Capture One tether wirelessly?
On selected cameras, on desktop and iPad. Check the wireless list for your model; USB is steadier.
Is there a way to use Capture One with an unsupported camera?
Tether with the camera maker's utility into a folder and have Capture One collect the files with its hot-folder option.
