I'm using my D7100 with the Nikon Fisheye 10.5mm f/2.8 lens on my camera and the focus ring won't turn.
I also use backbutton focus and it's a red square, it won't focus and turn green
Can anyone help?
Thanks!
update, never mind, I found the manual focus button on the camera body, duh, I tried to delete this post couldn't;t find how to
problem solved
