This filter is a game changer for photography. It makes my pictures look so much better and it helps a lot with the amount of glare that you may get from the water or car shields; things like that. I love how you can also screw on another filter along with it such as the UV filter. This filter will do wonders for you pictures.

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 was a gift, I received good references from the person who is using it.

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.

It arrived on time, excellent product, I tried it and it meets my expectations, very good quality

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.

As with most products from K&F, this is a great filter! I don't always use a polarizer, but it's great to have one on hand. One of the best things about this specific filter is that it screws in place and you can then manually spin it around to get the effect you're looking for. Anyone who has used polarized sun glasses knows what a polarizing filter can do. My pictures seem to have better color with this filter and it especially does a great job at removing glare. I'd recommend this to anyone that's serious about taking great photos!

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.

These make shooting cars much better. You can fix the ugly effects of the windshields by using a filter like this. Pretty much must have. Will also make a big difference when shooting water. K&F makes good stuff and this is no exception.
