I have just received a Nikon F5 Mirrorless Camera for Christmas and Im new to Nikon. I also received the adaptor and a Sigma 150-600mm lens. I keep getting the message that "cannot shoot because an unsupported lens is attached" I have been trying to do the update for the adaptor but simply cant get it to work. I have followed videos on You Tube and Nikon sites but it still wont update. Help!!
I also have issues with the camera even taking one picture with the lens that came with the camera. it just flashes green lights all over the screen. Even in Auto mode.
Im so excited to learn this system but right now Im very frustrated
