Well, it looks the same with my Nikon Z7 like before. SGP recognise the camera, I can connect, I can change ISO and set time, it looks fine. No errors. But no shutter release. Folders are created by SGP in the directory I want … but empty. I tried all three file possibilities. I put the camera in silent release and bulb (other option “time” I tried as well. OK, its hard to test when you have no camera.
Please be aware I am running Windows 10 Pro on latest version of Parallels Desktop (MacBookPro 21018) and on an other MacBook with BootCamp and Windows 10 Pro. mostly via Microsoft remote desktop.
Interestingly Windows Devise Manager show Z7 as mobile devise not under a COM port, anyway, I think SGP connects the camera. As said last time BackyardNikon can set time, aperture and ISO. Please let me know if you need more details.
