The Sensei PRO 49-55mm Aluminum Step-Up Ring permits the use of 55mm threaded filters on lenses with 49mm filter threads. It has large side knurls to provide a more textured grip when mounting or removing it from a lens. This step-up ring features a lightweight aluminum alloy construction with a corrosion-resistant, matte black, hard-anodized finish for durability and to minimize reflections.

I like it. It's really unobtrusive and doesn't affect the pictures at all, but if I had one complaint it would be that the threads on the larger side are a bit dodgy, it's easy to skip a thread so be super careful threading filters or hoods onto the stepped up side. I actually wouldn't thread a hood onto this, and after threading a filter on I back it off just 15 degrees or so to make sure it doesn't bind.
good stuff well made. Solid
* I’ve only used this step-up ring a couple of times since receiving it 3 weeks ago. The selling point for me is the outer ridges on the ring.
I bought this adapter ring so I can use an old polarizing lens which I still have from a previous camera system. I especially like this adapter because of the knurl sides as it makes easier to grip it. It's a high quality product.
Knurling is worth it.
Great quality. I can now use my 55 mm filters on my 49 mm lens. I do not have to buy all new filters.
