This offers great value for photographers looking to protect their lenses and enhance image quality. The MCUV filter reduces haze and UV light for clearer shots, while the CPL filter helps reduce reflections and enhance color saturation. Both filters are well-built, easy to attach, and provide excellent image clarity without distorting colors, making this kit a practical, affordable addition to any camera bag

The quality of the product is too good. The case is perfectly constructed.

I am very satisfied with this filter set 82mm MCUV+CPL. Really was astonished how good premium looking package. Nice to keep in hands and see that company cares about positive emotion to grant their product buyers. Quality of filters is outstanding - precise fit for Lumix S 24-70mm f2.8 lense. Just tested for picture sharpness without/ with UV/ with CPL/ with UV+CPL. First three positions not able to see any picture degradation, but with UV+CPL very slight lost of sharpness. Worth to mention that no color cast change for UV filter. And the last positive shock - delivery was so fast, I do not expected it yet. So I do not look anymore for other companies ND,CPL, UV filters as K&F Concept satisfied my needs!

Excellent idea to put the kit in a compact case, which protects them very well, and that I can now carry in the same camera case, and what I like is that I can add new filters in the same case, instead of carrying a large box for each filter.

Very happy with this new presentation, highly recommended.

Full disclosure: I received this filter system at substantially reduced cost in exchange for my unbiased review.

I just picked up a new Canon RF 100-400 lens that's got some pretty good glass but isn't L quality. Although I have a good B&W CPL filter that fits this lens I've never been very happy with the color cast. I've tried other K&F Concept glass before and was very impressed with the neutral color cast so decided to try out this polarizer kit.

I really like the engineering in this kit. This kit comes assembled as a compact sandwich with front and back machined metal caps. All of the caps and filters are clearly marked with filter size. There's a little storage pouch to help protect the filters and your other stuff when you toss this in your bag.

I tried another K&F filter previously and while I was very impressed with the glass I was far less impressed with the machined aluminum frame. Unlike that previous filter these attach to my lenses easily and don't bind. In practice the knurling on the filters make removal quite easy and in the case of the CPL adjustment is very smooth. There is perceptible resistance but no hint of binding or free movement that you get with cheaper filters. The feel of this filter is quite nice.

The thin profile UV filter is MRC coated to reduce glare and improve cleaning. This filter imparts practically no color cast at all. When held against a white background I can't discern any difference between filtered and unfiltered white. I don't ordinarily use UV filters since most of my lenses have better front elements than any filter I own, but in the case of the RF100-400 I will probably leave the UV filter on the lens since it doesn't have the same quality coatings as my other lenses.

The CPL is quite a bit thicker, but not so thick that I'm going to worry about vignetting since I'm mainly using these with medium to long telephoto lenses. All CPLs will affect color to some degree. Depending on the amount of polarization and the angle of the sun they will typically darken skies and change the color of water, sometimes dramatically, so it's difficult with a CPL to determine what color cast may be present. Using the same white background test I can discern an ever so slight cast versus the adjacent white background that seems to have a bit of a brownish tinge to it but could simply be the result of the light loss through the CPL. In test photos I could discern no perceptible cast at all. It's close enough to neutral that I don't think it's going to have much of an impact on color correction in post.

All in all really nice filters and a pretty good value to boot. Recommended.

Most of my lenses are professional quality glass, meaning they cost a small fortune. As such, it is terribly important to me that the filters I use do not reduce image quality or sharpness - I pay a premium price for this with the lenses I choose. I also want that glass well protected from scratches and dust so a UV filter, at the very least, is a required part of my kit.

While not an expensive model, this is an excellent set of filters on par with the best I have used to date which cost upward of $80+ for a UV filter only. I have another brand that has been serving me well for UV, but I wanted to add a CPL filter and I was also hoping the coatings on this set would be better. I have included photos straight out of the camera (just some quick test shots) to show how clear the glass is and the amount of contrast and clarity this set provides.

The set comes with caps for both sides of the filters - you can opt not to use one of the filters and know it is well protected by the metal covers. They can also serve as lens caps on the filter set which is nifty and I am thinking of using them as such because dust gets under the lens cap that came with the lens.

I found the filters to be very easy to clean and they don't seem to attract dust like my other filter does and the cat had the audacity to rub his snotty nose and furry body on the lens as I was trying to grab a shot. I did not find any vignetting at any range for a 70-200mm lens. Without the CPL filter photos tend to be a bit washed out in RAW and this filter has corrected that very nicely. They screw onto my lens easily and are lightweight which is nice as well - the filter these have replaced was not nearly as nice in either aspect and which cost nearly as much as this whole set for UV only.

I found the advertisement to be spot-on regarding the product and don't feel the need to add those kind of details here. There are also some other really great reviews showing the product itself. Hopefully this review adds some helpful details with the filters on the lens and sample photos with the kit in place. If you are looking for a great filter with both UV and CPL, this is an excellent option.

I’ve been a photographer for years and for a few of them a pro, but in all that time I’ve never encountered a nicer filter presentation or a better polarizer. The filters arrive sandwiched between two end caps both of which are precisely machined from aluminum. There’s no plastic here or faults or shortcuts in the machining process. I got these 49mm filters for use on a Leica. If ever there was a set of accessories that match the feel and sense of that camera brand, this is it. I was, to put it plainly, blown away.

While the UV filter strikes me as every bit what I want in such a filter, which is mostly a lens protector with no image degradation, but I have no way here to test such filters. I can test the polarizer because doing so is an easy home test. It’s simple: take a snap of your monitor with the polarizer set both to minimum and maximum. Please see the images that should be part of this review to see the results.

Note the test image is of the Zones from 0 to 10. I set the camera to have it just clip on 10 and let the 0 – 6 go as they will as an absolute test of this filter. The method is to see, at maximum polarization, how much of the 8s, 9s and 10s are let through the filter. Average filters will if the test is performed correctly, even show some leak through under 8. This filter not only completely filtered out the 8s and 9s but the 10s as well. I’ve never seen this level of performance before.

The images show the test pattern with the polarizer set to minimum (zero really) partly set to on and fully on. You can see a bit of the monitor’s bezel at full on because it’s at a slightly different angle than the screen so would be filtered out at a slightly different rotation angle.

It’s one thing to create a superb presentation but it’s another to have the filters perform at a level that matches this presentation. These filters do. From here on, when I’m in need of filters or photographic accessories, I’m shopping this brand first.
