Comments about Cokin 37mm Extension Ring:
We bought this to use with the Makayama Movie Mount for iPad due to the complaint that the lens mounting threads were plastic and easily stripped and that there wasn't enough space for a wide angle lens or a macro lens to attach. We super glued this onto the mount and now have a metal on metal thread to mount our lenses and the extension needed to allow us to mount whatever lens meets our need. Excellent buy.
