Product came as shown, works great. I mostly bought it to protect my expensive 85mm lens.

It fits perfect and does what they say it will do for your pictures. Cuts down glare

I was afraid to try this because of the mixed reviews, but this filter is just fine! I'm a hobbyist so this filter works for me. No weird colors or vignettes, just nicely filtered photos.

My first experience with the K&F Concept filters was with the purchase of a light pollution filter I've been happy with, particularly liking the grippy knurl added to the edges of the filter. After accidentally scratching my Hoya NXT Pls CPL 82mm filter which is more than double the cost of the K&F filter, I decided to purchase the K&F Nano Series CPL filter and see how I like it. Moreover, I also chose to go ahead and buy a 95mm version as well, to replace a Pro Optics (Adorama house brand) filter that I thought might be a lesser quality filter. Both K&F filters arrived today and a visual inspection of them reflects a quality product as I expected. However, one minor complaint is that I like the round K&F filter case which as a rigid plastic insert that appears to be grooved to support holding any of various sizes of filters securely in place in the case....that is, perhaps for a range of filter sizes, K&F may be using the same case to save manufacturing costs. However, while the 82mm filter arrived with that same case, the 95mm filter was in a more common, square plastic case with foam cutout to hold the filter. Still fully functional, just not as nice as the case provided for the 82mm filter. I don't expect to see any problems with the cheaper case, but it is the type that frequent use could find the plastic hinge wearing out eventually; I simply favor the 2-piece round case of the smaller filter.

I am not a pro, I like photography and I am doing it as a hobby. Didn’t want to spend $100 for a expensive filter. Went with K&F for the price. High quality materials. Very slim . I was impressed. Got it in 82mm for tamron 24-70 g2. After getting this filter looked at K&F products and got few more things.

Good quality.

Perfect fit

Love the pictures we are taking now with our camera

Sort of okay

For the price, I use the K&F Concept Filtre on all my lens and they do the job. I will not pay more for lens filters because i'm not a pro, so for me, they are really really good for almost anybody who wants good quality at a reasonable price. Full recomanded. L.B.
