I recently purchased the K&F Concept 67mm Circular Polarizers Filter Super Slim with 36 Multi-Layer Coatings and I'm so impressed. It's amazing how much of a difference this filter makes to my photos - in terms of clarity, sharpness and colour vibrancy. It's super slim, yet incredibly strong and durable. I love the 36 multi-layer coatings which give me amazing results every time. The images are crystal clear, thanks to the high definition coating. The colors come out vibrant and the polarizing effects are stunning.

This is a really nice polarizer and it works fantastic, as you would expect at this price point. It really just looks and feels high quality. Just be very careful when installing that you don't crossthread it, because I apparently did and now the filter is stuck on my lens :-( I will be leaving it on all the time because the camera shop I took it into said they are likely to break the filter trying to remove it. I don't think that is a fault of the filter though, just me not paying enough attention when I was putting it on.

Tested for video on my VG30 and works like a charm. It comes with a nice carrying case. Remember: You need to install on the front of your lens and then turn clockwise or counterclockwise so you can align properly and get the elimination of reflection that you are looking for.

I'm really no expert when it comes to filters, but of the dozen or so I own this is far and away the highest quality. You can feel the build quality the moment you screw it to the lens. It's incredibly lightweight but doesn't feel at all flimsy, and the threading allows for super smooth application and removal.I use polarizing filters more than any other as I live in a country that has near constant sunshine, so I've had plenty of chances to test this filter since I received it. The results have been just as good as I'd expect given the price. This thing beats the pants off my cheaper filters.

Got this to improve the image quality when I am out and about in the evenings taking pictures by the coast here in Newport Beach, CA. The filter was really easy to install onto my Canon EF 70-200 2.8 L lens, and it is very easy to maintain. The pictures came out stunning, especially from the water. I am in love with this lens filter, which is my new daily driver. Worth.

If you're used to cheap $10 filters just to protect your lens the price is eye watering for sure.But this is a quality filter from top to bottom. I normally ignore packaging aesthetics but thats the first thing that stood out. I thought there was a watch inside. From box to the filter pouch - Quality. They even threw in a cleaning cloth. Normally youre on your own with that.As for thr filter itself, doing a side by side with my cheap filters there a noticrable difference in detail. The filter itself is textured and grooved to reduce need for a filter wrench. The glass even spins inside of the ring so you dont overtighten. The 67 thread covers a wide range of lenses I have but Ill be using this for landscapes. One small knock on this is that theres not much depth to the filter so my lens cap doesnt securely settle in and ultimatley can bump off.Still one of the best filters out there.

I've been a fan of K&F Concept for a long time and have a lot of filters. Especially in the beginning, the cheap products were a real boon for my wallet. I simply couldn't afford expensive polarizing filters, ND filters, or adapters. However, they impressively demonstrate that K&F Concept can also be absolutely high-quality with this filter series.

I can report that just unpacking the filters is a real pleasure. Although this doesn't count directly into the review, it immediately gives off a completely different feeling than with the brand's other product series. It continues with a very attractive and haptically convincing case, which allows the filter to be removed via a tab.

But now on to the filter itself. I already have several polarizing filters in use, but none of these filters really convinced me as much as the Nano-X PRO. The workmanship is simply excellent, the weight is comfortable in the hand and the thread is fun - when screwing on and even unscrewing again. Most people will be familiar with it, cheap filters like to stay in place. The optical performance, which is ultimately important, is great. Reflections are skilfully filtered and there is also no distortion of the actual image. The look that is created is simply great. When you do some magic in post-processing, photos of cars simply look amazing, a completely different level. I can therefore make my recommendation without hesitation.

The filter is packaged in a small design object. The bag is well thought out from front to back and is just as well designed. But: a lint-free hard case would be much better. Unfortunately that was nothing.

A filter is always a compromise. I put a layer between the object (light) and the lens. As a result, quality is inevitably lost. In this case, the loss is very low, which speaks for the very good quality of the glass. The reflection of the surfaces is visibly reduced.

The ambitious price matches the performance of the filter. However, I don't use the filter bag, but use a hard plastic box - as always.

I'm really no expert when it comes to filters, but of the dozen or so I own this is far and away the highest quality. You can feel the build quality the moment you screw it to the lens. It's incredibly lightweight but doesn't feel at all flimsy, and the threading allows for super smooth application and removal.

As soon as you unpack it, you notice that this filter is of very high quality, as it comes in high-quality hard cardboard packaging. A very stylish and practical case is also included. The filter itself also looks super high-quality, scratch-resistant and works wonderfully!
It is very easy to screw onto the lens and also rotate it, although this is a bit difficult. But that doesn't mean it slipping either!
The price is quite high, but anyone who is willing to pay that much will have an absolute top product!
