Very nice standard filter set consisting of a UV filter (clear) and a CPL filter. The two filters come assembled and have a threaded metal lens cap on each end.

These are ultra-thin filters that are less likely to cause problems like vignetting at the edges. Very well made, with machined aluminum construction on both the filters and the lens caps.

The CPL filter is a bit darker than what I'm used to, so it's better for outdoor daylight shooting than indoor.

The UV filter is the best I've ever used, crystal clear with no bluing or other artifacts - perfect, 100% clear. I always keep the UV lens on my camera lens for protection since it is so clear. Works well with stacking additional filters.

The threads all work flawlessly and the CPL makes for smooth rotation adjustment.

Great deal on this starter filter set.

*Photos do not show the UV filter as it was on my camera at the time.

K&F has been a great company that my husband and I always go to when it comes to camera accessories. We used this brand for a similar filter in the 85mm size and now that we have a different lens we went with the 58mm polarizing filter. It's super thin as they say and it works really well. It helps with exposure movement and portrait shots as less light gets into the lens when you're looking for a moodier vibe and reflections are reduced. Kind of acts like an ND filter and adds a little more contrast and color.

tested this 82mm polarizing filter for photo output on different lenses, natively or via step-up rings. It screws on and off without any problem as long as it is not at an angle. I have put it on and removed it a good fifteen times without the slightest problem, so the filtering is good. As with any CPL filter of this type, there is a rotating part to adjust the intensity. The thickness is conventional, the grip is very good, the optical treatment too. The 82mm lens cap is a big plus, especially if, like me, we use a filter on several lenses of different diameters, it holds well. The mini lanyard that comes with it probably won't be useful, I don't know anyone who leaves their cork hanging on the end of the lens anyway. And as a bonus, it comes with a microfiber cloth, I have dozens of them but they are of high quality so it is always welcome. For €48 at the time of this review, we have a CPL filter that falls between the entry-level and the pros, but this model still does the job perfectly.

CPL filter (polarization filter) is a must for ambitious photographers. The company K&F Concept supplies a filter that comes with a lens cap, lanyard and microfiber cloth, a set that meets even the highest demands. I screwed the filter onto my OM system camera with a 58 mm zoom lens. It is not too easy to turn, so it does not move by itself in the camera bag. Since it is also quite inexpensive, the set gets five stars.

The K&F Concept Polarizing Filter 55mm CPL filter impresses as usual with its high-quality workmanship from K&F. I could not detect any disturbing influences on my pictures with this filter either. The effect of the filter is rather subtle, but it is good for reducing reflections. Overall, I can recommend the filter without reservation. So if you are looking for a simple CPL at a great price, you can't go wrong with K&F.

This circular polarizing filter worked unexpectedly well to remove unwanted reflections and glare. Images were clear and colors appeared much richer. When using the polarizing filter, images are a little darker, so always shoot RAW for professional results and easy editing. By rotating the filter, the effect of the polarizing filter was visible in the viewfinder, which made composing my shots very easy. The build quality seems good and it feels pretty sturdy and well made, but it's not a 5-star CPL filter. Rotating the filter wasn't smooth or easy. Overall, it's not perfect, but it's good value for money and is a great CPL filter for long exposures.

I bought the K&F Mark CPL filter holder as a replacement for the MK 2, which was quite cumbersome to remove and install the polarizing filter. The magnetic polarizing filter is now easier to change.

There are 5 stars for the entire system due to the good price/performance ratio.

I am pleasantly surprised by the build quality of the filter.
As expected, it's a CPL, so polarizing, and it does the job very well.
Can't wait to try it in real life for landscape and maybe some portraits depending on the situation.
