52mm True Color Ultra-Low Reflectivity Polarizing Lens Filter | Waterproof Scratch Resistant CPL Filter Polarizer Lens Filter with 28 Multi-Coated (Nano-X Series) FC704

I have other K&F products and have been very pleased with them. They offer good value for the cost, perhaps better value than the cost. This filter, which I have for my Canon 24-105mm L lens, is very high-quality. The case that the filter comes in is not sized specifically for the filter size but it has rubber guides with a space for each filter size so that the filter does not move around inside the case. I gather that this keeps costs down a bit since only one size case needs to be stocked. Included with the filter is a microfiber cleaning cloth, nice to have. The filter has a very low-profile bezel and threads very easily onto my lens. The rotation is smooth but no loose and it stays in place once it’s in the position I want it to be in. The grip Is textured and easy to move into position. The build quality is solid. As for the performance, it works great. It cuts glare as well as I could expect. Perhaps a darker polarizer would allow less glare but it would also not allow as much light in that the K&F does. Not much of trade-off for me, allowing more light than a darker polarizer is a plus for me. The colors look very natural even with the boost in saturation. I notice no color cast as I have with some other polarizers I have. It has a nice pop to the color. At this price point, I think t competes very, very well with other filters costing far more. It has 28 layers of coatings and construction is top-notch. It operates smoothly and threads easily and produces great color.

Great product. Compact, excellent built. Did a lot of landscape and urban photography with this filter, I have decided to keep this filter on my lens permanently. The lens effectively cuts down reflections and glare from water, glass, and other reflective surfaces, resulting in clearer and more vibrant images. Colors appear richer, especially skies and foliage, without looking overly saturated. The polarizer part of this filter rotates smooth, it is very easy to install or to remove the filter from your lens. No loss of sharpness encountered. The reason I got this filter is the ability to enhance contrast in outdoor scenes. Landscape photos have more depth, and cloud details become much more pronounced. The filter performs best in bright daylight and is a valuable addition for anyone who frequently shoots nature, travel, or outdoor portraits. This polarizer lens is a worthwhile investment for photographers looking to improve outdoor image quality. Its performance, durability, and ease of use make it a reliable accessory that can significantly enhance photos in the right conditions. Highly recommended

I've been using this K&F Concept 67mm CPL filter on my Tamron 18–300mm lens (Sony A6700), and overall, I'm happy with it. Let me be upfront: don't expect a dramatic, sky-goes-dark polarizing effect. What you get is a fine, refined improvement — reduced glare, cleaner colors, and noticeably crisper images. That's exactly what I expected from a quality CPL, and this one delivers. I'm attaching two sample shots — a moth orchid (Phalaenopsis) in the indoor setting and a moon image from the park — both taken with this filter and a Tamron zoom lens. The crispness in both images is real and noticeable. The orchid petals show clean detail without petal-surface glare, and the moon image has sharp, well-defined edges. No color distortion on either shot, which tells me the 28-layer multi-coating is doing its job. What I like: No color cast or distortion — "True Color" lives up to the name Image crispness is a genuine improvement Smooth filter rotation, solid build quality Threads cleanly onto the 67mm Tamron barrel One trick for finding max CPL effect: Point at the sky, lower your ISO until zebra stripes appear in the highlights, then slowly rotate the filter until the zebras disappear. That's your sweet spot. It takes practice but works reliably. One complaint: The original Tamron lens cap does not fit securely over the filter. It sits loosely and will fall off. Pick up a spare 67mm cap — it's a cheap fix but an annoying oversight when you're out in the field. Bottom line: If you want a color-accurate, well-built CPL that adds crispness and subtle polish to your shots without breaking the bank, this is a confident buy. Just keep your expectations realistic and grab a replacement lens cap. On 5/21/26, I am updating my rating to 5 stars due to the outstanding customer service from K & F. They promptly reached out and gifted me a protective cap at no cost. I'm very impressed—thank you, Anna.

This is a great option for a high-quality CPL filter without breaking the bank. It makes the blue really pop for sky photos and great for removing annoying reflections on things like grass and leaves. I did not notice any color accuracy issues while using it. The construction feels good. It threads easy and smooth on lenses. I also appreciate the notches on the filter to make adjustments are different sizes then the part that threads into the lens. Rotation of the CPL is smooth. The case that comes with it is a one size fits all, so it was a little larger than my 72mm filter. However, I liked how it came with a hard plastic case and inside the case are rubber ridges, so the filter is not sliding around. I would highly recommend this filter.

I've been very impressed with this K&F Concept True Color CPL filter. The build quality is excellent, and the slim frame fits my lens perfectly without causing any vignetting. The glass is crystal clear, and the ultra-low reflectivity coating does a great job minimizing glare and unwanted reflections. What really stands out is the true color performance. Unlike some CPL filters that add a noticeable color cast, this one keeps colors looking natural while still providing the benefits of a polarizer. It deepens blue skies, reduces reflections on water and glass, and improves overall contrast without making the image look overprocessed. The filter rotates smoothly with just the right amount of resistance, making it easy to dial in the desired effect. The multi-coating also makes it easy to clean and helps repel dust and fingerprints. If you're looking for a high-quality circular polarizer that delivers sharp images, accurate colors, and solid construction, this is an excellent choice. I would definitely buy it again.

The K&F Concept CPL filter has excellent build quality with a solid metal frame and a smoothly damped adjustment ring that stays firmly in place once set. It feels premium and precise in use. In terms of performance, it delivers noticeably richer sky blues and deeper color contrast compared to shooting without a filter, and far more natural tones than cheaper off-brand CPLs, which often add unwanted color casts. Reflections are well controlled, and the overall image looks cleaner and more vivid. Even in harsh light, the K&F shows virtually no ghosting or flare, making it a reliable, well-balanced polarizer that combines sturdy construction with impressive optical clarity.

Changed how my outdoor shots turn out. Reflections on water and glass disappear when I rotate it, skies go from washed-out to deep blue. Solid construction, threads on smoothly, and autofocus never missed a beat with it mounted. Great addition to my gear.

Fuji X100V: I did not realize that I needed a CPL, it was not something I really considered until trying it out. Now that I have, it really is a game changer for some specific scenarios. When shooting the sample images of the lake that I have added, if I wanted to achieve a bluer sky and less water reflection, the only way would be to reduce exposure typically through the exposure compensation dial. This would come at the cost of reduced exposure across the entire scene. With the K&F CPL, the blue sky is more intense and the water has less highlights and yet.. the rest of the scene's exposure is not reduced, the color and exposure remains. Even the grass is more vivid. Both images shot (Manual, 1/250, F/4, ISO 200). Some Notes: This works really well to deliver reduced highlights, glare and maintain rich colors. I initially was shooting in Aperture priority but noticed I had better results in full manual. The filter goes on easy without any issue and is easy to remove quickly also. Since this is a CPL, the outer ring will spin. And since the CPL ring lives on the outside of the filter element, I cannot use my lens hood when using this CPL. So to that extent, it require some forethought when using. K&F has another CPL that is significantly less than this one, but this is touted at 'True Color' and while I can attest that this works very well to maintain color and exposure, I cannot speak to how well it performs side by side with the other CPL. All in all, this is a great addition to my kit and I cannot wait to use this with flash. One small issue is that while the filter case has an interesting insert that makes it useable for many different filter sizes, it is unnecessarily oversized and the hard plastic arrived cracked in my order. I do not see it lasting long so I will probably seek out an alternative case.

K&F concept, cosa dire nulla da invidiare come qualità costruttiva dei materiali e delle lenti. Usato con un Canon RF 70-200 e una R6 MKII. Ho fatto delle prove sia in pieno giorno che al tramonto da dei colori delle luci veramente fantastiche. Sono molto contento di utilizzare già da tempo i prodotti fotografici di questa grande azienda molto seria. Servizio clienti impeccabile, sempre pronto a rispondere a tutte le mie richieste ed esigenze, consigliandomi sempre il TOP per la mia attrezzatura fotografica. Consigliatissimo!

Este filtro polarizador de K&F Concept es excelente!!. Reduce los reflejos de forma muy efectiva, mejora el contraste y los colores, y no introduce dominantes raras, algo que se agradece muchísimo tanto en foto como en vídeo . La calidad es muy buena el cristal es limpio y nítido, el marco gira suave y no genera viñeteado. Se nota que es un producto bien hecho y pensado para durar.. He probado filtros de otras marcas y sinceramente K&F concept ofrece una calidad impresionante por el precio. Es una marca fiable y con productos muy bien acabados. Sin duda volveré a comprar

جميل جداً

Werkt naar behoren op mijn rf 50mm. Levering was snel.

This works really well, just rotate the filter to see some reflections disappear and make those aquarium photos a ton better. Serves as a protective cover for your lens though I never have any problems with glass, my lens cover does still go on but there's a slight gap between the lens and the filter still. Don't make the mistake of leaving it on if you do video though, it creates a strobe effect with indoor lighting and some banding in the sky outdoors.
