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 100mm Holder.
Standard Adaptor Rings screw on with a fluid action, thanks to the sturdy construction and aluminium screw thread. They are suitable for use with lenses with a focal length of 24mm or more (18mm with a crop sensor).
Standard Adaptor Rings are available in a variety of thread sizes to fit each of your lenses.
