@joemulihttps://www.youtube.com/watch?v=0ueyQtu0ouk Kali supplied this...he uses a camera cap but I just used black card stock taped to one of my extension tubes and put the hole in the very center. popped it on in place of a lens. I can see my shot if I use live view but not through viewfinder! good luck lots of fun! my shots are all handheld so far...I can see the benefit of a tripod...will work on that when I have more time!
