Tried it get it set up today with no captures. Z8 with a 150 to 600 Sigma, so I know the distance parameter will not work, so left it disabled. I then tried all the Af settings but no luck. Lens is set to manual. Using video mode. Nothing. I am sure I am making a basic mistake but even after watching a bunch of Youtubers and reading the manual I still am at a blank screen. Any ideas?
