Perfect fit

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

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.

Not bad for the dollar , worth the purchase

Works perfectly.

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 really like the solid feel of the ‘action’ when rotating the polarizer. I haven’t had a chance yet to use it in the field yet though.

The product is great but clearly it's already been opened. My 62mm came in today still in the plastic not so this 67mm.

The performance of this CPL is quite good. I am able to achieve the results I expect with it. This CPL has been out in the elements for a few dozen outings thus far without issues. The polarizing effect is strong enough that you are able to dial in the amount of effect you want in your shot.

I've used it for car photography by shooting with the CPL at various angles and then stacking the images for the desired effect.

I highly recommend this product.

As a Professional Photographer and now moving over to Video as a Hybrid Shooter and content creator I have a growing number of new Professional mirrorless cameras & lenses. With many lenses of different diameters it is first and foremost important to protect the lens elements from damage. Then decide on what specialty filters that will help you with your composition & image making. From UV, circular polarizers, and Neutral density filters, K&F Concept Professional Optics makes great glass. In my many years of use of different brand name filters, it is my opinion K&F Concept will give you the BEST bang of your BUCK. Buy one today, try it out and see for yourself!
