I love these magnetic filters. I did have to get some step-up kits for it as my lenses are NOT 77mm, but a step-up doesn't cost a bunch.

The magnetic attaching feels great and holds on perfect. Even swinging the camera around really quickly doesn't loosen the filter or let it fly off the camera which would be a nightmare. Was one of my biggest concerns switching over to these filters. The pouch it comes into is also wonderful to keep them all together. Glad I wont be searching for them forever or losing them. I've already recommend many of my photography friends to pick this up.

They screw on pretty smooth it have a quality threads, and it work just fine. Perfect for someone who's only going to be casually using their step up rings, I am a professional photographer & I was looking same filter Ring Adapter & I order this product which is very helpful for me when I use multiple filter with my Nikon 5300 camera lens. During photo-shoot many time we have to change camera lens along with filter also, so using this ring it is very helpful for me, these rings get there job done, and don't get stuck. Please note - these are step-Up rings also have Step Down Rings total 18 rings.

⭐⭐⭐⭐ This step-up adapter ring is made entirely of metal and is very well made. Everything is clean and not spicy or otherwise bad in any way. We have the 67 to 77mm variant and can now use all 77mm filters with the 67mm lenses, since we originally ordered them for the 77mm lenses. The filters can be screwed on without any problems and hold on securely. The ring also holds firmly to the lens even after months. Highly recommended for the current price! ⭐⭐⭐⭐

Most of my filters are 82mm in diameter, but I have several lenses with a 77mm filter thread, so I need this adapter for them. It feels good, is very thin and does exactly what I need it to do, so I'm very happy with it.

tried it on my last shoot for one of the biggest brands and it worked perfectly! helped me make the place look more interesting and have the focus on the topic! It is a bit difficult to work with such filters as not every lens gives unique results. However, when you hit the mark in combination with the right lighting, it works so well. I also got the anamorphic filter and can't wait to use it on a new shoot! Other points worth emphasizing: I have invested heavily in the competing brand prismlens fx; I own almost every filter but one thing they are missing is the 82mm filter and K&F Concept hit the spot by offering their filters in 82mm. A reduction from 82mm to 77mm presents no problems, whereas 77mm to 82mm creates a lot of vignetting.

Normal step up ring that works

Bought for a Sigma Art Sony 24-70 and the Sony 28-135 (with Step Down), it is now permanently on my lenses. Additionally, having an ND and a polarizer on the same filter is a really nice surprise, especially at this diameter. For video recording and holding at 1/50 or 1/100 in broad daylight, this is best. A highly recommended essential.
