have used this product on 2 Sony lenses: 28-70 and 55-210 when water and snow-covered mountains are photographed. Skies are deep blue and glare eliminated.

got this becaused it's low priced and multi-coated. You can tell it's got the multicoated glass because the reflection is greenish. without the coating the glass is reflective and white. so you want more light to go thru without glare or refeections off your camera lense.

shoot a lot of outdoor content and the polarizer helped with minimizing the small amount of glare the camera picks up. I saw a lot of complaints about it getting stuck to the lense but I had zero issues taking it on and off. It has its limitation but for the price its a great introduction to what a better polarizer can do for your shots.

Good quality polarizer, bought it for my kit lens on my R50. Most of my photos use this polarizer. Smooth to turn, but also not too loose so that it doesn’t feel cheap. Would highly recommend buying from this company.

neutral-density circular polarizer is a must for photographers in its role of disappearing glare and reflections from images, and darkening colors (like the sky on occasion) that need to be darkened and lightening colors that need to be lightened. It makes the difference between a wall-worthy photograph and a meh-worthy photograph.

It perfectly fits my Ulanzi Anamorphic lens! I like how it transformed the images and videos a few notches higher. It also gave me the ability to manually adjust based on the environment. I like it. Price is okay too.

ordered this K&F Concept 43mm Ultra Slim Circular Polarizer Filter to use with my Fuji XF 35mm f2 lens. After lugging around a Fuji GFX100s and a set of GF prime lenses, I decided to try something different for a casual walkaround camera. I ultimately decided on a used XPro1 and a 35mm f2. My shoulders and back are so happy! The only problem is that all of my filters are designed for the much larger GF lenses. I usually stick with 77mm or 82mm filters and use step rings for lenses with smaller diameters, but I don't even have a step ring that fits the XF lens. With a 16MP crop sensor, files from the Xpro1 won't stand for the same level of editing that I typical apply to my GFX files. So, it's important to get the shot as close as possible to ideal instead of relying on "fix it in post." This K&F Concept CPL did not disappoint. It does not introduce any distortion, nor does is add a color cast. It rotates smoothly and does an excellent job at eliminating reflections without causing any vignetting. A few other reviewers have expressed difficulty removing the filter, but I did not run into that problem. I own other K&F Concept filters, and I would say that the overall quality of their products has been improving over time. If you do get a sticky filter, though, the slim nature of this CPL will make it difficult to remove. I do own a set of filter wrenches, so I tried using one on the CPL even though it was not stuck. I found that the wrench was able to grip the slim portion of the filter that screws into the lens with no issues.

have worked with a number of K&F Concept products, including some of their other filters and I have come to recognize them as an inexpensive brand with mid-range products. I have a lens with a 62mm thread size and more than once I wish I had a CPL for it. Now I have one that fits it and I am very pleased with it. If you are looking at this product and reading reviews, you already know why a CPL filter is important - in a very concise summary, it cuts reflections. Some are more effective than others and some are garbage. This one works well enough for my purposes. I often need one of these for dealing with reflections on either water or windows. Depending on how directly the light source shines on either of those surfaces determines how well it cuts out reflections. The more direct the reflection of the actual light source, the less effective a job the filter does. It seems to work on par with or somewhat better than other inexpensive filters I have used with other lenses - it cuts most of the reflections. It is not perfect but it works well enough. The amount of filtering is variable and the outer glass can be rotated to increase or decrease the amount of filtering. This is a standard feature. The rotation is smooth and I haven't felt any catches or grinding as I turn it. This is an inexpensive CPL filter with mid-range performance. If this was more expensive I would expect better performance, but for the cost I am more than pleased with it.

used this CPL recently during a trip through a winery. I wanted to help make the sky not look so washed out and this CPL filter works great. The effect is fairly subtle but it did make a difference. I'm going to try this out when I take a trip to a nearby river next. As it was stated in the listing, there's no vignetting in the photos thanks to the very low profile even if it has an adjustable ring. If you're looking for a good CPL filter to add to your camera kit, I'd highly recommend this one.

This polarizing filter is a good bargain. Well made and the copy I have does not have any color cast ( a common problem with parsing and neutral density filters). When rotating the filter, it's nice and smooth. The rotation is a little tight but will probably loosen up with use.
