Will mount any lens from approximately 18mm - 82mm. One knob adjusts the size, the other tightens it down. These are great for playing around with barrel lenses, or any lens really.
As you can see, one knob went missing at some point in history and was replaced. The new thumbscrew operates perfectly.
Asking $300 plus shipping. (Lensboard is not included.)
