Sits protectively and doesn't get in my way by causing problems with images.

Excellent product

like the look and especially the quality. It's a good filter and great value for money, at least for now. I had read other reviews that alluded to it not fitting, having to use a lot of force and not at all. I just put it on and took a video of the moment so you can check at least in my case and with a Sigma 24-70 2.8 DG DN Art what fitted perfectly and smoothly. Best of all, I've already protected the target.

Nowadays, the biggest advantage of a UV haze filter is to protect the front element of the camera lens. There's also haze correction, but the need for film for blue reduction isn't the case with digital cameras. The bigger reason is that today's post-processing software can filter as much haze as the photographer desires, which no UV filter can do. The need for protection is real. Even if it means keeping the front elements of your lenses from getting dirty or splattered, these filters play a role. I was wearing this filter when I made a misstep and splashed into a small river that soaked the camera. I felt a lot better about my clumsiness knowing I wouldn't have to face the delicate chores of lens cleaning when I got home. However, a filter in the light path must be of high quality, otherwise the image will be degraded. I'm far from having a lab to test glass here. The best test I could think of was easy. I would take an identical picture with and without the filter and then compare to see if I have any issues. Yes, it's raw, but it's what I have. Please see the included image. To create this, I set the camera on a tripod, set the exposure manually as a best estimate, and then took two pictures — one with and one without this filter. I took the RAW images, randomly cropped a portion of one and pasted onto the other. Both are labeled. I then compared the two and focused on the area where they merged. I drew a black line at the approximate location of the join. I didn't do any post-processing. These are the RAW (DNG) images straight from the camera, converted to JPEG just for posting here. I did my best pixel peek on both images and didn't notice any distortion from this filter. In other words, it does exactly what I want it to and has now earned a spot on my lens.

This is a well built UV filter. I did this to attach a non-weatherproof lens with an internal zoom mechanism. A UV filter on the front provides extra protection from the rain for an upcoming trip. The anodizing on the metal ring appears to be of good quality. This and the knurling on the outer ring offer a very good grip when installing and removing. The threading corresponds to the thread on the lens cavity. The filter glass is crystal clear. I found no noticeable degradation between shots taken with and without the filter attached. For the same shot and lighting, my camera didn't adjust the exposure values between turning the UV filter on or off. This is a good UV filter for those of us who like a little extra protection for our lenses.

I have the 67mm on my Sony a7iii on my 85mm Sony lens. It's so clear you don't even know it's on. The image quality is exactly the same without any problems. It blends into the camera and protects your expensive lens from damage. To assemble it, you turn it in circles several times to tighten it. No instructions are provided, but pretty much self-explanatory. More information on their website. There is also a 1 year warranty period if you register the lens from the date of purchase. These can be replaced at a much cheaper cost than having to buy your expensive lens again!

I was trying to update the UV filter on my telephoto lens and this looked like a great option. The glass is very clear and doesn't cause any problems or artifacts with my photos. It's a really nice UV filter for $20 (at the time of this review) and the quality and materials seem very good, especially for the price. I would recommend that!

The filter arrived well protected and appears to be of really good quality. I usually use Marumi, Hoya and B+W filters but this seems like a great and more affordable alternative (at the time of this writing). Feels light but good construction Nice ridges in attach/remove size. I installed it on my Tamron 28-75mm lens that I use on the Sony 7R III and after some test shots I didn't notice any distortion, flare or other negative effects. The sharpness was not affected either. Very happy with this filter so far. Protects the lens and doesn't seem to affect image quality. Will definitely try other K&F filters.

put something on all my outdoor lenses to protect them and I like to use a UV filter to reduce a bit of the usual haze shots in beach-like environments. I usually use something more expensive, but settled on the K&F Concept 52mm MC UV protection filter. It arrived in a slightly wider filter box than normal. The box was slightly larger as the filter was packaged in a lockable plastic box with foam protecting the filter from damage. I viewed the filter under a magnifying light and it was flat and smooth with no scratches or oddities. It fits my 45-150mm lens perfectly and it really is a low profile filter. It doesn't seem to affect the sharpness of the lens, doesn't affect clarity and I'm happy with that. I am quite happy with this UV filter. Is this filter as good quality as one of my $50 B+Ws? Possibly not, but then again, the B+Ws cost more than twice as much, and you'd have to be a pixel-peeper to notice the difference in image quality. If I look at my pictures 100%, I'm satisfied.

I install a UV filter on all my lenses. Turns out my 70-300 flew naked!! So I chose this 67mm filter to protect the front elements. I do a lot of travel shooting as well as weddings and protection from bumps and such is key. It's far cheaper to replace a filter than an entire lens! This filter element offers a neutral passage while protecting the front glass and the threads of the expensive lens. Recommended!
