perfect for what i needed - allows me to use 77mm filters on my 67mm lens without having to buy more filters.

I've used this ring only once so far but it was a pleasure to use and the results have been excellent. For an outlay of just £5 I have been saved having to spend over £40 for a second circular polarizer - excellent!Just for the record, this ring was mounted on a Hoya Pro 1 Digital Protector 67mm filter (which graces the front of my lens) and onto it was mounted a Hoya Pro 1 Digital 77mm Circular Polarizer - everything threaded together beautifully - excellent engineering!

Works ok for adapting lesser used filters between lenses. A little scratchy threading, but works for my infrequent needs. Very inexpensive alternative, but may end up buying a high end and smoother threading one if using very often for my 5D III and L lenses.

Purchased the step-up ring for a planned trip to the Eastern Sierra's. The ring was utilized for neutral density and polarizing filters. I like the fact that I did not have to take the UV filter off. I simply screwed the step-up ring onto the UV filter. The set-up was very easy. One time I had a hard time unscrewing the ring from the neutral density filter. A few quick taps to the side of the ring and filter, and it quickly unscrewed. I also bought a 52mm to 77mm step-up ring.

I was in the process of purchasing a circular polarizer to work with my 67mm when I found this product . Since I already own a high quality 77mm polarizer, I went ahead and purchased this, although I was not sure of how well it would work. I have been waiting for weeks to try it at the lake, as I wanted to capture the beautiful, colorful scenery there. Wow! Photos were great! Very pleased with the ease of use and the fit and finish of the product. The adapter seems to be of very good build quality. Bottom line: I am really glad that I purchased the adapter and will not hesitate to purchase this brand again.

Works fine but it's threads seem to be slightly off from my Canon 100mm 2.8 L Macro lens as it is pretty tight when screwing it in.
