Fotodiox WonderPana XL 186mm Anodized Black Metal Aluminum Step-Up Ring

The WonderPana XL Step-Up Ring provides the freedom to use and share 186mm round filters on all of your regular lenses. Fotodiox step-up rings are made with precision out of premium grade aluminum. Every ring is inspected to ensure smooth mounting and is polished and finished with anodized matte surface for professional appearance. Step up rings allow larger sized filters to fit on lenses with smaller sized filter threads.This step ring will allow the WonderPana186 filters (with a 186mm thread) to fit on lenses with a 77mm, 82mm or 145mm threaded front. Smaller step up rings can be used to adapt to smaller sized lenses (ie; if your lens has a 58mm filter thread, the 58-77mm and 77-186mm step up rings would be used together) and can be purchased separately.
