<p>Hi - I own this lens for my RZ67 Pro II and the Floating System ring, used for extension tubes, is stuck. It only jiggles a little in the No. 2 setting. Does anyone know how to reset it? I believe it's supposed to move freely no matter what it's mounted on (or not at all).<br>
I have the No. 2 tube. Mounting it on that, or without, doesn't make a difference. Still won't move. Thanks for any advice...<br>
