55mm 2 in 1 Filter Kit MCUV+CPL Filters, HD/Waterproof/Scratch-resistant/Anti-reflection, with Upper and Lower Metal Lens Caps & Storage Bag Nano-Xcel Series

I'm very impressed with these filters! Not only do they look high-quality, but they feel high-quality too. The weather conditions near me haven't really allowed for me to go out and get some good nature shots with this set yet, but the test shots I've taken near my home have come out looking great. The only thing worth noting is that I keep accidentally partially unscrewing the filters when I go to adjust the CPL - I'm sure it will just take some getting used to.

I'm really pleased with the inclusion of the lens cap and rear cover - it makes for slim storage, and I appreciate that as I often like to travel with a small camera bag.

Overall, I'm really happy with this set, and I would definitely recommend it.

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.

Nice quality, and the polarizer does great, on sunny days.

Great product with a great price. Better than expected

All I NEED to say about these is that I've removed the Hoya and B+W filters from my better lenses, and replaced them with K&F filters. I'm going to add that this filter "kit" is so well built and thought out, with the included METAL caps front AND back when not in use, are so nice that I've now bought several and will look to K&F for my filters BEFORE looking to what I used to consider my "go-to's" in the past. I love these things. Recommended!!!

This is a great filter set that includes both a UV and CPL, but also a nice case to protect the filters when off the camera. I have been using them for over a month and found them to be high quality and perfect for my needs. Would highly recommend based on the value and overall quality.

Product as described. Well packaged.

They came with a protective back and front lid for your protection. I like that you can actually stack 2 to your camera. I highly recommend them.

This gives my high end Hoya, sing ray, and B&W filters an absolute run for their money. I can see no difference whatsoever with K&F vs filters from these other manufacturers in terms of image quality on both my canon rf L series glass, and my rare Olympus 35-100f2.0 zoom lens, which might be the sharpest lens I've ever used.

It's a useful kit having both the protection filter and the CPL filter, which appears to introduce no color cast to images. Very pleased with these products. If I need more high end filters, I will look at product from this brand 1st.

Have fun with these filter tips
