The “K&F Concept Nano-K Series Black-Mist 1/4 Filter 72mm” comes in a plastic box that you first have to figure out how to open. Even when you've mastered it, it's still cumbersome. There are also 3 microfiber cleaning cloths, individually wrapped in sleeves. I chose a diameter of 72 mm in order to be able to use as many of my lenses as possible with it using adapters. The filter has a corrugation several centimeters long on two opposite sides, so that it is particularly easy to grip. As the English name "mist filter" roughly translates to "fog filter", the filter creates an effect or mood like fog, especially with lights. In addition, this filter makes the skin appear a little softer. I'll start with the second point, with the skin: The effect is minimal and should be seen more as a positive side effect. Significant wrinkles/skin imperfections remain visible and only slightly lose their sharpness. It's different with lights. That is also the main purpose. Here the effect is very clear as the pictures show. The filter gives lights a glow or aura. The image with the sharp edges is without the filter and the image with the glow and smooth transitions is with the filter. Conclusion: an inexpensive Black Mist filter for beautiful lighting effects. Only the box is suboptimal. The filter gives lights a glow or aura.

I don't know how many camping lights I've used over the years...a lot. I have a whole box of camping lights in my garage and this one by far is my favorite. It's light, small, has great versatility and brightness. Everything I need in a lamp. It's made out of sturdy, durable materials, has a heft to it, and can be used in a million different ways. Also, it has a cool design.

What more can I say, the Step Up Ring is 1A compatible with my Canon Eos 600D (see picture). It fits like a glove, the zoom can be adjusted perfectly and a polarizing filter can be screwed or clicked on. But does the metal material keep what it promises??? But for around €7 you can't complain :-)

ordered the K&F Concept Step Up Ring 72mm to 77mm to be able to use my 77 filter as well. The ring is cleanly processed and the threads are cut absolutely cleanly, so it can be screwed onto the lens and the 77 filter onto the ring without any problems. No complaints, everything great. I definitely recommend the ring.

The Step-Up Converter Ring was packaged well and shipped quickly. So far I'm pretty happy with the build quality. The ring is made entirely of metal and seems sturdy to me. In addition, the internal and external thread is properly worked. Thus, the adapter can be easily screwed onto lenses. With the help of the adapter ring, I can now easily use my larger ND filter on my smaller lens. Everything works without any problems, which is why I can finally recommend the adapter ring.

K&F Concept Step Up Ring for lenses, 58mm to 62mm, just under 5€ With adapter rings, only the precision of the production counts so that the threads mesh well. The ring from K&F Concept fulfills this very well. Now I can also use the filters from my 55-200mm tele. You should only note that if you leave the adapter on the lens, you may need a larger lens cap, as the smaller one no longer grips. Conclusion: Everything in order, price is right. 5 Stars

K&F Concept Step Up Ring for lenses: filter adapter ring made of metal for ND, polarizing filters, etc. Good quality, workmanship and price. The adapter can be screwed on and off my lens without any problems. The filter used also turns gently on and off.

It works on my Nikon with no problems, including the autofocus. I'm happy with that.
