WonderPana 145 Step-Up Ring from Fotodiox Pro – Anodized Black Metal Step Up Ring for 77mm, 82mm or 95mm Lens Threads to WonderPana 145mm Round Filters
The WonderPana Step-Up Ring provides the freedom to use and share 145mm 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 WonderPana filters (with a 145mm thread) to fit on lenses with a 82mm 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 58-82mm and 82-145mm step up rings would be used together) and can be purchased separately.
