M85x0.75 male to M77x0.75 female step-down ring (filter thread adapter), flat
This adapter allows using M77x0.75 filters on lenses with M85x0.75 filter thread.
It is made flat (shoulderless), so it is basically an insert into the filter thread to reduce it down to M77. This design prevents vignetting risk.
Made of anodized aluminium.
