52mm True Color Ultra-Low Reflectivity CPL Filter Polarizer Lens Filter Circular Polarizing for Camera Lenses with 28 Multi-Coated (Nano-X Series)

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 recently purchased the K&F Concept 77mm True Color Ultra-Low Reflectivity CPL (Nano-X Series) filter and have been extremely impressed with the results. The colors remain very natural and accurate, avoiding the color shift that some polarizers introduce. Reflections are noticeably reduced thanks to the ultra-low reflectivity coating, and the image clarity stays excellent. The build quality feels solid and the price is very reasonable for the performance you get. Overall, a fantastic CPL filter that delivers great color, strong reflection control, and excellent value.

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.

This K&F Concept CPL filter is great, I have already got 2 other K&F Concept filters from a few years ago, which are also very good and i like very mcuh ! It has "True colour" and maitains the sharpness of th!e image The filter has excellent build quality, and it has a solid metal frame. It has a premium feel to it and precise in use. It also seems to have great performance, much better than cheaper other-brand filters. It is easy to attach to the lens, very durable, and i think it is a very good "value for money" filter

I’ve been using this CPL Filter for a few weeks, and it’s been a solid addition to my gear. The colors in my photos look more natural and vibrant, and I haven’t noticed any strange color cast like I’ve seen with some other filters. It does a nice job reducing reflections and glare, which is really helpful when shooting water, glass, car, downtown buildings etc. Tt makes clouds look sharper and more defined while deepening the blue in the sky—it really adds a nice punch to outdoor shots. The build quality feels good—sturdy frame, smooth rotation, and the coating makes it easy to clean. It doesn’t seem to affect sharpness either, which was important to me. One thing I’ve learned: CPL filters work best when the light source (like the sun) is at about a 90-degree angle to your subject. Mid-morning or mid-afternoon usually gives the best results. I mainly use it for landscapes, skies, and cutting glare on shiny surfaces, and it’s been working well for that. Overall, I’m happy with it and plan to keep it in my kit.

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.

The K&F Concepts CPL filter feels solid and performs better than I expected. I was surprised by the noticeable difference in colors; the blue of the sky is more defined and the colors are more vibrant. It fits the lens perfectly and feels premium. Whenever I shoot videos, I do some color grading, and with this filter, I practically didn't have to make any adjustments, which saves me a lot of time. It offers excellent contrast and more vibrant colors, and it greatly helps with reflections and glare. It's a very well-balanced and well-built filter. The packaging offers good protection and includes cleaning wipes. It's definitely a very good investment and worth having. I highly recommend it.

Great CPL filter for the price. The K&F Concept 77mm True Color CPL feels well made, and I really like that the rotating ring is not loose. It has just enough resistance, so it does not move around easily while it is in my camera bag. The polarizing effect works very well and helps cut reflections nicely, especially on glass, water, and shiny surfaces. The image quality looks good, and the price is very reasonable for what you get. Overall, I am very happy with this filter.

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.

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

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.
