I have a strange problem with my new D850 and Capture One v11.1 on Windows 10. I don't yet have an XQD card reader so am reliant on a direct USB connection for the moment for importing files.
If I connect the camera and open File Explorer (not C1) I can see the D850 with the folders for the two cards and the subfolders with the images, and can copy the files from there to the PC as expected. So far, so good.
However, if I attempt to import directly into C1, the import window can't see either memory card and only shows the main D850 folder (and sometimes not even that until the camera is restarted) which it says is empty, with no subfolders.
After closing C1, Windows File Explorer then also shows an empty D850 folder until I shutdown and restart the camera, when the subfolders then reappear (but are still not visible in C1).
This behaviour is fully repeatable on two PCs and with both USB3 and USB2 connections and cables. The D850 appears to work normally otherwise on the USB3 connection, with all capture and remote functions seemingly fully functional.
I've just checked with my D3X and that appears to behave identically, so I doubt it's a D850 problem specifically (I've always used a card reader for D3X files so hadn't noticed the issue previously).
Am I missing something obvious here? A camera setting? Missing drivers? A bug in the C1 import procedure? Or am I simply expecting it to do something it's not designed to do? The camera manual is not helpful, neither so far is Google.
Any suggestions. comments or confirmation would be gratefully received. I'll raise a case with Phase One if necessary, but wanted to make sure it wasn't user error first.
Many thanks in advance.
