My camera is not connected to Capture One.
My camera gets frequently disconnected from Capture One.
The attached camera does not appear in Capture One.
IMPORTANT: If you are a Capture One 12 or 20 user running macOS Catalina, then please see this page for the issues related to tethering on this OS.
Before you proceed with the troubleshooting steps, please check the article on the basic setup for the tethered shooting workflow to define how your current setup could be adjusted.
The attached camera does not appear in Capture One
1. First of all, you will have to find out whether the operating system sees the camera.
- When using macOS, navigate to the Apple icon in the Menu bar and choose About This Mac -> System Information -> USB section. In case your camera is not listed, refresh the list. If the camera is still not listed, some hardware issue is likely to be there.
- When using Windows, navigate to the Start menu, choose the Device Manager, and check the USB section.
If the camera does not appear in the list, then check and replace the tether cables, remove any non-powered repeaters, check the things with a different camera.
2. Verify that Capture One is running as Capture One Pro/for Fujifilm/(for Sony)/for Nikon.
- When using macOS, go to the Capture One -> License in the main menu.
- When using Windows, go to the Help menu and choose License Information.
NOTE: If you are running Capture One in any of the following modes - Pro, for Fujifilm, for Nikon, or (for Sony) - it means that tethering is supported in these product variants. The only thing you have to verify is whether your camera is supported for tethering. Otherwise, please follow the steps below to check whether you have the cable of the appropriate length, your camera is set up properly, etc.
3. Make sure the proper camera type is enabled in Preferences > Capture > Providers. As a secondary troubleshooting step, enable ONLY the type of camera you are trying to connect. That will help to prevent any driver confusion and avoid any 'syntax error' messages. You will have to restart Capture One after changing any of these parameters:
- All: Verify whether your camera is on the list of the supported camera models by Capture One. Do not place a storage card in the camera. Check how to attach an unsupported camera.
- Canon: usually requires no special settings - A noted exception: Disable WiFi on the Canon 6D.
- Nikon: usually requires no special setting, some older cameras may need to be in PTP mode for USB rather than Mass Storage or MTP.
- Sony: use PC Remote as the USB setting.
4. Make sure the camera is set up properly.
5. Remove any storage cards from the camera as their presence often confuses the computer as to which method to connect to the camera. This is particularly relevant when using macOS Catalina, as a full memory card can cause a tethering session timeout.
6. Verify the physical connection. Use only a 3m USB cable (maximum) with no extensions. Try a new cable. Test a different USB port on the computer. Connect by using an externally powered USB hub. Make sure no other software like Image Capture, Canon EOS Utility or Nikon Camera Control is running.
7. Make sure that you do not have chained adapters.
8. Disable any power saving settings on the camera which could cause it to power off while tethered as this can cause a cascading effect across the OS and Capture One, causing a loop that blocks the camera from reconnecting.
9. If you are using Google drive, disable automatic backup and sync when you need to tether. Google drive will often intercept the camera connection before Capture One is able to connect. Even if you are not actively using Google Drive, uninstall "Backup and Sync with Google" as this will also prevent reliable connections. Dropbox service also can intercept the camera connection before Capture One is able to connect. Therefore, it is recommended that you close the application to ensure a stable and reliable connection for your operations.
10. Grant Capture One proper accessibility and disk access in Apple System Preferences. Go to System Preferences -> Security & Privacy -> Privacy. Unlock the window by clicking on the lock and entering your password. Then add Capture One by clicking the "+" button. Do this for both Accessibility and Full Disk Access options.
The connection is not stable and the camera disconnects frequently.
Test a new cable, another USB port on the computer, and a different camera if possible. Disconnects sometimes occur due to wear and tear of the system components.
Besides faulty cables and ports, disconnections have become increasingly common on Apple computers as operating systems are diverting power and resources from the USB ports to other areas of the computer. That is why a weaker connection to the camera may take place. The solution is to use an externally powered USB hub or externally powered USB extension cable. A good option is the StarTech 5m USB3 Active extension when used with its power supply.
