The Irix Edge 100 adapter allows you to mount the square filter holder on a lens with a specific thread diameter. The adapter is mounted by screwing in the adaptation ring into the front filter thread of the lens.
Irix Edge IFH-100 adapters are made from high grade durable aluminium with a matte finish. The adapter still has a front filter thread, so it is possible to use some screw-in filters at the same time as square filters.
