Fantastic set of step up/down rings for a good price! Really happy now I can shoot outdoors with all my lenses and only need the one ND filter!

Useful addition to any photographers camera bag if you own several lenses of different sizes. Allowing you to have one filter for all your lenses (buy the largest you can) and then use the rings to step down to your appropriate filter thread size, so no more needing the same filter in 3 or 4 different sizes!Well machined with smooth threads. Easily as good as any more expensive product. As always Neewer makes another great, reasonably priced alternative.Highly recommended!

I found these be pretty good.I have been in the engineering game a very long time now and I can see a little flaw or 2 but for the most part they are very good.To be clear they fit well thread screws wells pitch etc is perfect.They do exactly what they are advertised to do. faultless on my purchase and lenses / filters I screwed them to.Mix of hoya and sony E- mount + some neewer filterAgainst, they have no splines or knurl to help undo,But less bve honest with our selves if you want something tight you tighten it, if you want something to undo you nip it up, its all relative.I find nothin wrong with the engineering materials or finish. they work perfect arrived perfect.If you twist them together hard even a knurl or spline finish would not really help you undo them.

purchased to attach my filters to different lenses. Can never go wrong with Neewer products. Have to treat carefully but great quality at a great price

Thread is fine and I found best to rotate them backwards first to make sure they seat well and not cross thread.Of course they will stick once in place if only through thermal expansion not being the same as the lens body they attach to. Do not put on tight but so they just about bite. They should stay in place but be easier to get off after.

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

These rings allow me to use the same filter size on many different lenses. this means that for the filters which I only use occasionally I need purchase only the size to fit my largest lens.Although the adaptors cover most sizes there is no adaptor for a 46mm lens. This is a big omission as 46mm is a common filter size and so should have been included.The rings work fine and they screw in smoothly. But it would be very useful if each ring had roughness at least on part of its circumference to ease unscrewing as this can be quite difficult with the completely smooth surface.Because of the 46mm omission and the smoothness making difficulty in unscrewing I have given these a three star not a five star rating.

didn't actually workout for me with the sizes but I have kept them as it's a good bit of kit for them money plus well made.
