Hello, so I'm pretty new to Nikon but I currently own a D5300. I mainly use it for live streaming using a video capture card, but my problem seems to be the focusing. I use Af-f but it seems to over focus even when I'm not moving, and if I manually set focus, I cant show things close to the cam, or get up and move around. Is there any way I can adjust it to not refocus so hard while I'm streaming? Do I need another lens? Or a remote maybe?
