Another win from the folks at K&F! This circular polarizer is excellent and happily has found a spot in my camera bag!

Sure, I have other polarizers from other manufacturers at 1.5 - 3x the price and, at the end of the day, they all do the same thing. It comes down to materials, fitment, and the quality of the elements/film/coatings. For the K&F this ticks all of the boxes and is price competitive for sure.

The polarizer screwed right on to my workhorse Canon EF 27-70 2.8 L lens as well as my EF 16-36 2.8L with zero hang-up, drag, or grind with cheap filters often do. Once mounted, you can rotate the bezel of the filter to get the polarizing aligned for your use.

I have not done an extensive study on this to see if there is any colorcast or defraction however I have not noticed any anomalies while using the filter. And no, it's not a permanent fixture on my lens as more likely than not I am not needing polarizing.

The filter comes with one of the K&F lens cleaners as well as a spare lens cover (K&F branded) which is a nice spare.. also comes with a small lanyard. The filter and lens cover come in a reusable plastic padded storage box for safe keeping.

I have included a couple of photos of the contents of the packaging.
