I previously purchased this filter in a different size and was highly impressed. The slim design makes it almost unnoticeable, but the filter is still of high quality. The filter functions well. I believe this slim design also helps in the reduction of any impact the filter may have on photo quality, and color accuracy. The filter may also adds a layer of lens protection, in case of unfortunate situations like accidentally bumping into an object. This in addition to reducing dust on the lens itself. The previous iteration of the filter (67mm) proved to be very durable ( as it still sits on my lens). My most recent purchase (December 2025) had to be replaced, as it apparently spontaneously shattered. I discovered this when I was retrieving my camera from its bag (Lowepro), and heard the jingle-jangle of broken glass. My lens cap was still perfectly attached, hence my befuddlement. Overall, a quality product, despite the unfortunate occurance.

Very difficult to assess a filter but with this filter there doesn't appear to be any no distortion, no false colouring and images are sharp from the lens so you'd have to say the filter is good and fit for purpose.

I have these on at all times because they barely darken anything. Meaning high light transmission. I had to really look at some scopes to find a difference. I gave up and just assumed any light loss is meaningless. For sharpness, stopped down in the sweet spot with the new Sigma Art lenses, I can't tell a difference on my 42 mp camera. My Tamron 35-150 is pretty much perfect for 42 and 61 mp sensors, and its the same. Even the g masters my friends have shown it is pretty much the same with or without it. But, I can tell better contrast and micro contrast with landscape and city shape. It's basically dehaze in camera. And, a bit of clarity. I have had photography friends what I'm doing in editing to get clearer images, and it is using these and a cpl if I need to. Also, my lenses are expensive. They're insured but I would die if a front element got scratched. I work a lot of events and shoot video in weird places. Many years ago, I did actually trip and my Sigma 85 hit a rock. I didn't want to look. Luckily the lens was perfect and this filter took the hard scratch. Ever since, I buy knf concept nanox uvs for all my lenses. I spend the bit of extra money because the lens sharpness is intact. Color is all there. Dehaze in a filter. And, if a tragedy were to happen, I am out like $40 over $2,000. Or waiting forever for my replacement and insurance claim to go through.

I got the K&F Concept 82mm UV Lens Filter to protect my lens, and it’s been great. The glass is clear and doesn’t introduce any color cast or softness to my photos. I leave it on my lens all the time now, and it gives me peace of mind knowing the front element is safe from dust, scratches, and accidental bumps. The build quality feels solid, and the filter threads smoothly onto my lens without catching. It’s also thin enough that I haven’t noticed any vignetting, even on my wide‑angle shots.
