Haida Rear Lens Filter Adapter Ring for Sigma 15mm f/1.4 Fisheye DG DN Art Lens (Sony E)

Designed for the Sony E-mount version of the Sigma 15mm f/1.4 Fisheye DG DN Art Lens, this Haida Rear Lens Filter Adapter Ring allows select Haida filters to be installed behind the rear element of the lens. Simply remove the existing rear ring from the lens and install the adapter ring in its place. Then the corresponding filters made to fit this adapter ring can be easily installed and removed as needed. The adapter ring can be left attached indefinitely as it does not affect the operation or performance of the lens. It is made of aluminum and comes with a storage case.
