Works great. Very useful for my lenses.

Ok

Does what they are meant to and has saved me many times. All I'd say is sometimes they screw together very tightly and can be difficult to seperate. Still worth buying.

I use K&F ND filters and these step up/down adapters are a must for my different size lenses.

I'm so glad I found these!I'd bought a few different UV filters and ND filters and one polarising filter for various lenses, but it started to stress me out how much it was costing, especially for an ND filter that I will very rarely use, and that I'd have to plan around which lens had the ND filter rather than which lens was best suited for the shot. Then, I stumbled across these, and it's been a game changer. Luckily I already had an ND and polarising filter for my largest lens, so with the step up filters I can cover all of my lenses with both of them whenever the need arises.

Good robust quality, threads easily into respective smaller or larger adapter rings. Works well with my Nikon D7200, would highly recommend.

These aren't bad rings if you lubricate them slightly. They do stick if not careful. My first set was missing all the step down rings. i got these replaced but the second set was also missing rings so i ended up returning everything to buy elsewhere. Whilst i had them i tried the rings i did have and found they stick easily if not careful both to each other and more importantly to the lense or filter you're using it with. Quite dissapointing from a brand that i regard pretty highly and have many other products from.

These step-up and step-down rings are useful when you have a collection of filters you bought for use with your film camera and you want to use them to create special effects with your modern digital camera. You can use them fitted together to make a lens hood.
