I use these rings so that I don't spend a lot of money on polarizers and ND filters for all of my lens sizes. The investment in a solidly constructed ring like this one is well worth it when you count the cost of the buying those filters for every lens size.

I bought this step ring specifically to use my 77mm Circular Polarizer on my Nikon 18-70. This filter comes on and off with some regularity. The step ring threads on easily and filters go on and off with no effort. Tiny serrations make it easy to grip the step ring for removal if required. No vignetting but I expected none with a 67mm to 77mm. I?ve had no problems at all. The interior surfaces are a matte black finish that eliminates reflection. There are less expensive step rings available and if I was planning to mount a filter permanently I would have considered them, however I need to be able to mount and dismount filters quickly without the fear that they will be stuck to the ring and/or that the ring will be stuck to the lens. I got what I paid for and I?m happy with the product. Your mileage may vary depending on your driving habits and road conditions.

Very good quality 67-77mm step-up ring at a good price. The ring is thin and does not vignette.
