Tiffen 60B67SUR 60 Bay to 67mm Step Up Ring

Filter systems are an investment, and the Tiffen 60B67SUR exists to protect that investment across lens systems. If you're shooting with a Bay 60 mount lens and have a quality set of 67mm filters — polarizers, graduated NDs, UV protectors — this step-up ring is the mechanical bridge that makes them interoperable. Rather than maintaining separate filter sets for each mount style in your kit, a single ring unlocks the larger filter ecosystem. For photographers working across medium format or legacy glass where Bay 60 mounts appear, this is a practical necessity rather than an optional accessory.

The ring itself is machined aluminum — the same material standard across the filter adapter category for good reason. It's corrosion-resistant, dimensionally stable, and light enough to live permanently in a filter pouch without adding meaningful weight. Tiffen's manufacturing precision means the threads engage cleanly on both the Bay 60 bayonet side and the 67mm filter thread side, which matters more than it might seem — a poorly toleranced ring that binds or wobbles introduces micro-movement that can affect sharp images when using slow shutter speeds or long exposures with ND filters mounted.
