Neewer 18 Pieces Metal Camera Lens Filter Ring Adapter Kit - 9 Pieces Step Up Ring Setand 9 Pieces Step Down Ring Set for Canon Nikon Sony Olympus DSLR Camera, Black

These are very good and cost effective, my only advice is to make sure they accommodate the sign you are looking for:I have a 52mm lens and 58mm lens, the 52mm one was fine but there was no step up/down ring for 58mm, it goes 55-62. Which is wierd since there is a 52-55mm ring, so they could have done another 3mm stepup. Ultimately this was my fault, I should have checked before hand, and thus I pass on this tip to anyone looking to buy these rings... double check they will fit ALL the sizes you want

I bought these as I got a little fed up buying separate filters for different lenses. I now buy the largest filter that I need and then use the step down rings to match the lens filter size, and this set covers the whole range. They seem to be well made, and there is no sticking or gripping when screwing or unscrewing the rings in to the lenses

A really handy set of reducers/enlargers for filter thread. Good solid feel to them and they screw easily (with caution not to cross thread) onto the lens. Great range as well, so it seems to cover just about every lens filter size.

Light weight but very well made. Covers all sizes from 37 - 82mm. Can be used individually or in combination. Wasn't sure what these would be like, because of the price, very pleasantly surprised. A good product at a fair price

I wanted to use one size of filter on my lenses and this seemed to be a good way to do. So I bought a big filter and fitted the rings as needed, it works perfectly! As a bonus, when I'm not using a filter the rings serve as a small lens hood.
