@jamesstaddon I mounted the lens normally, then turned on my camera and stopped down the aperture a bit. I then pressed the aperture preview button, and then took off the lens while holding down the aperture preview button. I found a tutorial on Youtube. I am not sure if this is great for the camera, so I would definitely research it before trying. But it is a pretty neat trick!
Yes I will be! That would be cool!
