Yeah... bit quiet. I'm starting to wonder if I've asked a stupid question.
It's says adjustable back focus from 66 to 86mm so the back lens travel is 20mm. The lens surface is approx 9.7mm off the face of the T-thread. I assume there must be an optimal spacing between this T-thread and the camera sensor. That's what I'm trying to figure out. I can't seem to find much on Google either.
