There are several reasons for the camera not recognized/detected in Capture One:
1. Note that Capture One Express (for Sony)/Fujifilm does not provide the option for shooting tethered. Explore more differences between Express and Pro versions.
2. Capture One Fujifilm supports cameras from Fujifilm, Phase One, and newer Mamiya Leaf camera systems only. Similarly, Capture One (for Sony) supports cameras from Sony, Phase One, and newer Mamiya Leaf camera systems only.
3. If you have other than Sony/Fujifilm camera or want to use several cameras, check whether those are on the list of the supported camera models. You can purchase a license for Capture One Pro or get an upgrade in our store online.
