have been a fan of K&F Filters and many of their other photography products for some time and have come to appreciate the brand's consistency and quality. Most of my lenses live their lives with a K&F Concept UV protection filter on the front. I have sufficiently tested the transmittance and sharpness of K&F filters in the past that I now consider them a trusted brand. I am confident in their quality. And that's the point, right? Find a supplier you can trust to deliver exceptional quality. I use polarizing filters extensively, much more often than not. They are a multi-purpose filter that allows the user to add contrast and saturation, reduce glare and reflections, and to some extent, since they add neutral density, control exposure. There is little reason not to use them, except in low light situations. Another benefit of the 82mm size, and most sizes for that matter, is its cost advantage. The use of step-up rings allows it to accommodate a range of lenses that require a smaller filter size. This applies to filters of any size. In practice, the K&F Concept 82mm polarizing filter can be used on lenses with filter sizes from 77mm upwards, provided appropriate adjustment rings are used. You do not need to buy a separate polarizer for each of your lenses. The filter is solidly constructed from aircraft-grade aluminum and is typical of the high quality of K&F Concept filters in general. The damping of the outer ring is even and provides the necessary resistance to keep the adjustment securely in place. Since a CPL has no stop, when adjusting it it must be rotated in the same direction that you would attach it to avoid accidentally detaching the actual filter from the lens. K&F Concept uses AGC glass, formerly Asahi Glass Company, a Japanese company that is the largest glass manufacturer in the world. They also claim that there are 24 multi-layer anti-reflective coatings on each side of the glass, which are important for reducing internal lens reflections. In my testing, the filter lived up to the seller's claims. It polarizes light and the colors seemed "true," or at least to the extent inherent in the rendering capabilities of a digital sensor. This was affected by camera settings and the sharpening and dynamic range features introduced by the manufacturer. In other words, "True Colors" is subjective. Also, I did not notice any reduction in sharpness when using the filter. The physical properties of the filter are its relatively light weight, as well as the faceted chinas around the perimeter of the polarizing ring, which provide a better grip. I use an 82mm VND filter, which is 82mm in diameter, and the thread on the front of the filter, also 82mm, provides enough depth for the stacked filter to be securely attached. The K&F front lens cap that comes with the filter is on par in quality with any OEM lens cap I own. The clamping levers are easy to use, firmly spring loaded, and give a firm grip to the filter or the lens it is attached to. I also appreciate that the front threads on the CPL match those of the 82mm filter size, allowing the use of standard OEM accessories such as a lens protector. The filter comes with the lens cap, an adjustable lanyard, a high-quality microfiber lens cleaning cloth, and a plastic storage case. K&F Concept offers good value for money and doesn't cut corners.

have previously purchased one of this company's polarizing filters for my Nikon Coolpix P1000 (77mm size) and was very happy with it. This UV or "Skylight" filter is no exception and is another winner! It is well made and of good quality and shares some of the cooler features with the polarizer, including that it includes a lens cap with lanyard/carry strap as well as a microfiber cloth for cleaning. The filter itself fits perfectly with the threads on the lens of my P1000 and the optical quality of the filter seems excellent. Highly recommended!

regularly go out into nature with my dog and carry my Nikon D750 with various lenses, the most important of which all have a 77 mm thread. Especially in the forest and in the Harz Mountains, I always use a polarizing filter to reduce reflections from leaves and water. The only problem is that polarizing filters always absorb light and you have to extend the exposure time accordingly, which is a disadvantage if I want to take spontaneous photos of my dog. Up until now, I was skeptical about magnetic filters because I was unsure whether they would hold well enough when I was hiking through nature with the camera and the filter mounted. Accordingly, I welcomed the opportunity to test this filter from K&F as part of the Vine program. I have already had very good experiences with K&F products. Your program covers a very broad spectrum, but there are some of your products that are very high quality, but are aimed at ambitious amateur photographers precisely because of the lower prices. This filter is also one of the better products, which you notice as soon as you unpack it. The filter is very cleanly made, the magnetic thread and filter fit perfectly. The filter comes in a matching box, and there is also a lens cloth included, which is well protected in aluminum packaging. Overall, everything makes a very good impression. The thread can be easily screwed onto the lens, the magnet pulls the filter well into position and holds it very firmly, so that the filter can be easily rotated without slipping out of position. Since this is a slim design, it hardly affects the image even with the wide-angle lens at 16 mm. This filter has clearly put to rest my fear that a magnetic filter could fall off while hiking. It sits really securely and firmly on the lens. Nevertheless, it can be removed very quickly if necessary, which is much more convenient than the tedious unscrewing. For me, this is a significant improvement in the handling of filters in outdoor photography, where you often have to adjust your equipment spontaneously. I think I will now rely more on using magnetic filters, the test convinced me of their functionality. The filter performance is clearly in the better range of the polarizing filters that I use. There are really big differences in the reduction of reflections and color fastness, and you have to invest quite a bit if you want to have reliably good filter performance. I am very satisfied with the performance of this filter; you can clearly see how reflections are reduced when you turn it. Overall, this is another highly recommended product from K&F.

K&F Concept Polarizing 67mm Lens Cap. I like these lens caps because they are made of very high quality steel with polarizing glass to not only protect your glass (lenses) but also allow you to change the polarization by rotating to get the best possible photos for the lighting conditions. The lens also has several special coating layers to intensify the colors while reducing glare. I highly recommend the K&F Concept lens caps as I use the K&F on all my RF and older EF lenses.

Even though the screw-on solution is a bit tricky and it is unusual not to find a rotary lever for the polarizing filter, all filters work excellently on my D7000. I can't detect any aberrations, distortions, etc. That's all I need. The original polarizing filter from Nikon costs, for example, ALONE already about 150 euros, I have discovered nothing that can better. The brush is ingenious (just pull off the cap on the back and then pull the rubber stamp (not at the end)). The small bag is ebefalls super, so at least the parts do not fly, as usual, in breakage-prone hard plastic boxes in the photo bag around. I find the set as it is completely class. It would be better only with ner instructions, the manufacturer / seller probably assumes that all know what they have there, but is not true, a small note with a few tips on how it works or-. is handled (manual) would certainly silence many critics. When I read the reviews here, a manual is really missing, although everything is logical and easy. Apparently some do not even know what for and how to use the filters.

I would not follow the tip to use the UV filter as a lens protector (at least with digital cameras). These filters also have disadvantages with digital cameras, they can reduce the performance of the lenses under some conditions, modern lenses already have UV protection at the factory, double is not always better. The front lens is better protected with a sunshade.

I purchased this 82mm circular polarizing filter to use with both my Sigme 24-70 f/2.8 E mount and my Canon 24-70 f/2.8L II lenses. It's just a perfect polarizer for these versatile zooms.

The lens is extremely well made and the circular effect is smooth as silk when attached to the lens. The high-quality multi-coating ensures details in photos and videos without artefacts or haze and ensures excellent focus accuracy.

Polarizing filters have many uses, including deepening the color enhancements of skies and landscapes, especially in bright light conditions. In addition, the circular settings can be used to shoot through windows clearly and without reflection, and to take pictures or videos through water. For example, this filter can be used to capture perfect images of Koi (Japanese Colorful Carp) in a pond without light bouncing off the water's surface. There are other uses as well.

To operate, all that is required is to point a camera at the subject and rotate the outer plane of the filter until the desired effect is visible through the viewfinder... or on a screen. Easy peasy.

I own a number of K&F filters of various types including UV, ND and diffusers. I trust the company's products. This is excellent value for money compared to much more expensive polarizing filters such as those from B+W and Hoya while offering virtually equivalent performance. Fantastic!

It's an unequivocally high FIVE STARS from me, along with my honest and very warm recommendation. Improve your photography and vlogging! get this!

I now have this amazing filter attached to my Olympus 60mm macro lens. The lens has no lens hood, a bad front cap and obviously no filter. This is now on board, along with a tidy front cap and third-party lens hood. 46mm is a little small and fiddly, but this one has a really good knurled ring that feels good in the hand. The thread is also very smooth and positive. The color balance is imperceptibly different, so it doesn't bother when shooting in well-lit close-ups. I love the improvement on this brilliant lens. ricky

K&F Concept 77mm True Color Polarizing Filter HD optical glass, double-sided, 30-layer nano-coatings, circular polarizing filter (CPL), aluminum frame, water-resistant, scratch-resistant, fingerprint-proof I use filters... when I have to. Polarizing filters are among the filters that can make a real difference in terms of contrast enhancement/glare reduction in certain lighting conditions. It is important that I find this filter: - Excellent optical properties. Limited sharpness loss. (as good as it gets). - Neutral color - Adjustable polarization by rotating the filter as intended. - Thin. This filter is thin and should not cause vignetting in most cases. For the same reason, it can be combined with another filter without the risk of vignetting. While this is standard these days, it makes removing the filter more difficult than with thicker filters. - The threads are well formed and the filter screws on easily. - The light loss is about 1 stop, which is typical for today's high quality polarizing filters and better than the 2 stops of previous generations. Note for landscape photography: It is not recommended to use a polarizing filter with ultra wide-angle lenses in landscape photography, as they produce an uneven sky. That's a good filter. It performs above its price. Worth considering. Accordingly recommended.
