Excellent quality filter. The quality of the image is fantastic when properly used and exposed. I use this for long exposures with bright spots in the frame. It's particularly effective with light trails. The construction of the filter is high quality.

This UV filter is a solid choice, offering both protection and ease of use. The case is quite large—possibly oversized—but it has thoughtful elements like foam notches on one side to accommodate almost any filter. It also includes a vacuum-sealed wipe, though I haven’t opened it yet.

One standout feature is the ease of installation. The filter has two notches positioned 180 degrees apart, making it much easier to screw on and off compared to others I’ve used. With some filters, I’ve struggled to get enough grip and had to resort to using my flat palm, but that’s not an issue here.

I purchased this as a simple insurance policy for my lens, and past experience has shown that UV filters can be a real lifesaver. Overall, I’m happy with this and would recommend it to others looking for a filter with practical features.

I got this for protection while traveling and bringing my RF 28-70 f2 lens. It’s well-made, doesn’t feel like it will bend, and does not have any negative optical effects that I can see.

I’m really impressed with the K&F Concept 77mm Shockproof & Ultra Low Reflectivity UV Filter. I got this to protect my lens investment, and it delivers far beyond just being a basic protective layer.

First off, the build quality is excellent—the tempered optical glass feels solid and gives me peace of mind when I’m out shooting in unpredictable environments. I also love that it’s waterproof, scratch-resistant, and fingerprint-repellent, which is huge when you’re switching lenses or adjusting settings on the go.

What really stood out, though, is the ultra-low reflectivity—I honestly didn’t expect such a noticeable difference. My images have stayed sharp and vibrant, with no weird reflections or flares. The 28-layer coating clearly does its job.

I use this on my 77mm lens and it fits perfectly. It’s slim enough not to cause vignetting but tough enough to handle real use. Highly recommend this to any photographer looking for high-end protection without sacrificing image quality!

This is a great K&F lens filter to protect your camera lens from shock harm, water, dust, scratches, oil, and fingerprints. This K&F Concept shockproof tempered UV filter is made by importing quality Japanese AGC glass. The ultra-low reflection MCUV filter reflectivity is controlled at 0.1%, which effectively reduces lens reflection and vignetting, resulting in a clearer, more contrasty and detailed picture. Great UV filter overall.

K&F concept does it again. Not many third party companies can manufacture something that partners well with OEM equipment but somehow K&F manages to put out quality products time and time again. I’ve never used this type of filter before and was a bit skeptical at first. The quality and elegance of the photos takin with this filter have taken my photos from looking good to looking like well thought out quality work. It’s amazing the subtle yet professional difference this filter makes. Well worth the money.

Nice black mist effect! Quality is good and no complaints. These filters offer a good value for the price without sacrificing much of anything noticeable in functionality compared to much more expensive filters.

This is a superb filter. Well made. High quality.

Nice effects in the studio and for walks. K&F has been making some of my favorite camera accessories. This lens filter is one of the nicer ones I've been able to use from them and find it easy to recommend to anyone in need of a diffusion filter.

High quality, comes with one of the nicest filter carry cases I've ever used. The lens case is padded and made from leather. It provides great protection for transportation.

Completely consistent with the supplier's description. Well packaged, these filters are flawless and suitable for my use. The price is a factor in its favor.

This isn't the first product I've tested from K&F Concept, and I'm starting to get to know them well, and each time, it's a solid product. It's not ultra-high-end professional gear, but for demanding amateurs, the price/quality ratio is often excellent. I've never been disappointed by them, and this filter is confirmed.

I was looking for a UV filter that would both protect my lens (Olympus Pro 40-150mm F2.8 mounted on an OM SYSTEM Om-1 Mark II) and not impact image quality, and this one pleasantly surprised me. I got it at 62mm for a zoom I use a lot outdoors, and it definitely does the job.

First of all, the build quality is impeccable. The frame is made of aluminum, lightweight but sturdy, and the ring screws on without forcing. The glass seems of good quality, and the coating works. It's a nano-coating, supposed to repel water and fingerprints, and limit reflections. And in practice, it works: no ugly halos or weird flares to report, even against a somewhat direct light source.

I compared the filter with and without it on several different outdoor shots, and I didn't see any loss of sharpness or contrast. The reflectance curve (seen on their product sheet) confirms this: over 99% of the light passes through, so there's virtually no loss in the final result, even in 4K or on demanding sensors.

The filter is also advertised as scratch- and impact-resistant, with a glass hardness rating of 9H. Okay, I'm not going to play the tester who tries to scratch their product, but it has already survived being transported without a case, in my camera bag, without a single mark, so that's a pretty good sign.

In short, this is a great choice if you want to protect your lens without compromising the quality of your photos. You don't need to be a pro to appreciate it, and it prevents damage to a lens costing several hundred euros. Sure, it costs a little more than a basic filter, but here you're paying for real optical quality, and it shows.
