The Benro 37-67mm Step-Up Ring for Camera Lensesfrom Benro 37-67mm Step-Up Ring for Camera Lensesis an aluminum-constructed ring that enables you to adapt a larger 67mm size filter onto a 37mm diameter lens, therefore, many different filter sizes can fit on your lens. On wide-angle lenses, the ring's low-profile prevents any vignetting in the image, and the flat black finish on the ring minimizes reflections, which would cause lens flare as well. Additionally, the knurling on the edge allows you to have a firmer grip of the ring when you're putting it on a lens.

Q: 2. I noticed that the individually sold 67-77mm Sensei step-up ring is sold as (and is marked) "Sensei Pro". But, the rings in this kit are not marked with the "Pro" designation. What is the difference being as the single 67-77 "pro" ring costs 50% of what this kit costs??? Thanks!

A: The pro rings are matte black and have knurled edges.

Q: 3. If I want to go from a 37mm lens to a 77mm filter would I stack all these rings together?

A: It is possible, however I would advise you to try using as few rings as possible to avoid vignette. As well, you will need to make sure that the filter you are using is absolutely clean to avoid focusing issues.

Q: 7. Can I use this StepUp on a Fujifilm X30?

A: No; 40.5 is too large to go on the X30. It is frustrating to try to attach anything to these little Fuji lenses. I ended up buying a lot of miscellaneous caps, hoods, step up rings, and filters. I finally gave up and purchased the Fuji hood that came with a clear filter (size not specified but perhaps a 40mm) and a pinch cap. It seemed like an unreasonable price, but it works well. All the other filters and step up rings and caps are part of my estate.

Q: 8. Can the PolarPro 67-82 step up ring be used with a Breakthrough ND filter?

A: The Sensei 82mm Step-Up Ring Kit has the same pitch thread size as Haida filters; therefore, you can connect Haida ND filters to any of the Sensei step-up rings.

Q: 10. Meant to ask about attaching Cokin 67 mm adapter on this step up ring to work on a 55 mm lens with the P Cokin Filter holder?
