A:Answer This is a hard one to answer, as I do not own a Nikon (though I have owned many Canon and Sony cameras, which I've tried using with the Cam Link 4K). What I CAN say is, your listed camera (Nikon D3500) is not listed as a "known" compatible camera. This doesn't mean it won't work, but it means they've not tested it and can't guarantee it. Assuming there isn't some Nikon software that lets you see a "clean" feed without a lot of delay, you would need either something like this device, or a different camera. To see if yours is compatible, it needs to meet the below requirements (from Elgato's site). Good luck!
1. Your camera needs to output video via an HDMI port. Most cameras have a mini or micro HDMI output jack.
2. You need to have a cable that connects your camera from the video output jack to a standard HDMI port.
3. Connect your camera to any HDTV or HDMI monitor. Check that the HDMI output is "clean" — meaning whether the extra information overlays can be disabled, Most likely you'll need to check with your camera's manual to find the menu item that turns off all overlays.
4. For DSLRs, check whether your camera can be operated continuously. Check with your camera's manual whether you can disable battery save mode. Some cameras also always power down after a set period of time of continuous operation, to safeguard the camera's sensor.
5. Can your camera be powered by an external power supply while outputting video, and while mounted on a tripod?
