Adaptor Rings are a simple but important element of the LEE System, enabling the same holder and filters to be used with different lenses. Simply screw it onto the lens and then clip-on the Seven5 Holder.
Seven5 Adaptor Rings screw on with a fluid action, thanks to the sturdy construction and aluminium screw thread. They are available in a variety of thread sizes to fit each of your lenses.
There is also a ring specifically designed for the Fuji X100/X100s (listed here).
