Adapter back focus Lock
Just got our new PL mount clamp form richard. Works like a dream. Simply screw the adapter in until the set point you wish and then lock it off with the locking bolt. It clamps around the broader part of the adapter as we discussed in Las Vegas but Richard wanted to try the rest a little differently. I think he did a good job too. It's a very snug fit and the tests we did were great. What do you think Dave?
