I haven't had a chance to properly use then yet. But they look like they'll do the job and are well made.

Ordered Thursday, delivered Friday, used Saturday on my new Fuji lens for use with close up filters. Well made, fitted perfectly, great purchase. This was my 2nd purchase from K & F. I was just as satisfied with my first.

They feel good on my lens and I have stuff from these before. Will be using them more often.

Does what they say they do. My only question is why don't they include a 49-52?? They completely skip that set. I mainly purchased so I could use my 52mm Variable Nd filter on my 49mm lens and with this it goes from 43-52? Skipped a lens set completely so for that I give them 3stars, besides that it's great. Just look out of you need a 49mm step up as the 43-52 will not work for you.**Edit** Very Fast response from the company and there intentions were very positive to fix the issue. They get 5 stars.

Perfect quality and fit. I did proactively use a very light application of Vaseline to be sure they don't seize up but that's on me.None were out of round or otherwise incorrect. All pieces were received in separate plastic slip covers which was appreciated.So no chance of them showing up already seized up. Packaging was correct for the product. I would buy from this merchant again.Job well done!

Machining on the threads may not be quite as precise as on some more expensive adapters, but these work fine for me. If you are concerned about the threads binding, you could always get a set of camera filter wrenches (which is a good investment to have anyway). These are slim enough that they do not cause vignetting, and they allow me to use fewer filters on more lenses by adapting the size of their threads to fit. I feel these are a good bargain for the price, and cover all the thread sized that I need.

Rings were machined well and attach to my lenses smoothly. This package had a few of the common sizes for my lenses and worked out well.
