Comments about B + W B + W Step-Up Adapter Ring 67mm Lens Thread to 77mm Filter Thread.:
I bought this so I could put an existing 77mm polarizing filter on my new Nikon D90 lens. The ring is beautifully made and threads easily. I'm glad I spent the extra few dollars for a high quality product.
Comments about B + W B + W Step-Up Adapter Ring 67mm Lens Thread to 77mm Filter Thread.:
Does good job for stepping down 77mm filter for use on 67mm lens so don't have to buy two filters for same purpose. This brand is well made but a bit pricey.
Comments about B + W B + W Step-Up Adapter Ring 67mm Lens Thread to 77mm Filter Thread.:
I have several expensive filters (circular polorizer, graduated greys, UV, etc.) that I use with my Canon 70-200/2.8L IS lens that I would like to do double duty on my Mamiya 43mm medium-format lens. The 67mm to 77mm step-up ring will allow me to do so with no image loss, vignetting or flare.
Comments about B + W B + W Step-Up Adapter Ring 67mm Lens Thread to 77mm Filter Thread.:
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.
Comments about B + W B + W Step-Up Adapter Ring 67mm Lens Thread to 77mm Filter Thread.:
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.
