Hi all, I just bought a Konica AR 40 1.8 which is a fantastic little lens, but the adapter I picked up seems to have a problem where it lets the lens focus past infinity. True infinity is reached one or two degrees before the end of the focus rake, so it's a little annoying to have to remember to rake to the end and then back up a little if you're scale focusing. I read that you can shim an adapter to increase its distance from the sensor which would effectively fix this problem, but I have no idea how to measure how much shim I need. The adapter itself looks like it can easily be shimmed: It has three screws which separate the Konica end from the E-mount end, and can easily be undone and propped up slightly. Any advice would be appreciated. Thanks!
