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.

Great for landscape photos and more.
Includes: Polarizer & UV Protection filter, front + back lens cap, storage bag.

Had to pick up the size that would benefit me most. Ended up with the 62mm set.
The would be the largest size, based on my current lens selection.
Have a few lens that were smaller and have the solution for that.
Pick up the K&F Concept 18 Piece Filter Ring Adapter Set.
(made of the same aviation aluminum alloy)
The perfect companion to this set.

All filters and caps are made of aviation aluminum alloy.
Have anti-slip teeth on the edges CNC'd into the sides for better grip when turning.
The CPL & UV are clearly printed on the side without the grooves (in bright white letters)
CPL filter is a a bit thicker than the UV as it has a adjustable ring.
Perfect threading all the entire four piece.
The CPL & UV optical glass both have Nano coating that's keeps them waterproof and oil resistant.
Even when I put a nice big oily finger print on the glass, it was a quick wipe to clean.

Filter caps are in the K&F colors.
Black with a orange stripe.
Top cap also has logo in orange.

Storage.
When not in use the filter set is very compact at around .75" thick.
Place into the draw string storage bag.
A dark gray to black soft bag with a orange draw string with plastic ends.
Would easily fit in a pocket or placed into a gear bag.

Overall.
Applying and removing the filters from my lens was smooth.
For outdoor shooting both filters can be used at the same time.
Just as they said, no vigenetting or dark corners.
Circular Polarizer worked perfectly. Just turn until you get the glare is removed.
See photos of the bird bath.
This will permanently go into my gear bag. Recommended.
Hope this was helpful.

I'm relatively new to photography so I'll leave it to others to weigh in on the technical aspects of these filters. They worked great for me at a recent shoot at the beach. As you can see, the CPL cut down on the glare while shooting straight into the sun and water, but the details are still sharp. Instead of the usual plastic box, they have two metal caps that screw on each side, and the filters screw together also. It makes for a nice compact size that should fit easily in your camera bag and comes with a small cloth bag to help protect them. I'm very happy with these filters and I suspect you will be also.

Very nice standard filter set containing a UV filter (clear) and a CPL filter. The two filters arrive sandwiched together, with a threaded metal lens cap on each end.

These are ultra-slim filters which are less likely to result in problems like vignetting around the edges. Very well made, with machined aluminum construction on both the filters and the lens caps.

The CPL filter is a little darker than what I'm used to, making it better suited for outdoor, daylight shooting as opposed to indoor conditions.

The UV filter is the best I've used, crystal clear, without any blueing or other artifacts - perfectly, 100% clear. I keep the UV lens on my camera's lens at all times for the protection since its so clear. Works well with stacking additional filters.

Threads all work nicely, and the CPL provides fluid rotational adjustment.

Great deal for this set of starter filters.

*photos don't show the UV filter since it was on my camera at the time.

This is great to have. They stack well together even with the lens cover. The quality is impressive. I got it for my sigma 16mm and Sirui anamorphic lens, both are 67mm for my Panasonic BGH1 micro 4/3. I switch then around between them depending on the shoot. So far, it’s been a good experience especially with the cpl whose presence is more obvious. The uv I leave on the outer for protection of tens as well as the cpl. Good quality product.

good
