K&F Concept 72mm Circular Polarizers Filter 28 Layer Super Slim HD Multi-Coated Circular Polarizing Filter (CPL) Lens Filter

Verry diffecult to remove from the lens due to bad design i.e. notches (rough portion to grip) is reversed. Unable to fit the lens cap due to grove not having enough depth, Lens cap keeps falling. I won't recomend K&F CPL made in Japan to any one.

This is amazing, really cheap and really good, high-quality glass, I accidentally dropped it and it didn't even have a scratch! works very well, and the ring isn't too loose. However, if you tighten it a bit to much,it will be hard to remove.Recommend using a rubber band to remove it in that case,although it is very very good, recommend it 10/10, you won't be disappointed!

The rotation of this CPL is very stiff compared to other filters. This causes the filter to tighten on the lens mount. Plus the mount ring is very thin and difficult to grab when mounted on your lens.As a result, the filter is difficult to remove. You will very likely need a filter wrench to remove it.Returned

The filter itself seems fine. A bit dark. But, the case it comes in is absurd. It's clearly designed to be a universal (has markers going up to 82 mm), but I purchased for a 40.5 mm., which means the case dwarfs the filters. Its hard heavy plastic, so not something you want to add to your camera bag for no reason. Silly that they didn't include a case that actually fits each filter. [I annotated someone else image to show the size of the case.]

I use to switch filters often. But the fixing ring of this one gets stuck in the lens and it takes some time and effort to be able to remove it.Otherwise, the image quality is good for the money.
