52mm 2 in 1 Filter Kit MCUV+CPL Filters, HD/Waterproof/Scratch-resistant/Anti-reflection, with Upper and Lower Metal Lens Caps & Storage Bag

I tested the K&F Concept filters on a Canon EOS 5D Mark III with a Canon lens.
I am very satisfied.

The filters are very well made. They are delivered well packaged. It is also practical that you get them right away in a well-padded bag and can thus store them well protected in the photo backpack. So the filters can also get no scratches and you always have the filters of one size together.

Also supplied is a cleaning brush.

The filters are absolutely accurate fit. This is not self-evident for filters of this price category.
I received the filters on a test basis which has no influence on my rating.

Ideal for landscape photos and more.
Included: Polarizer and UV protection filters, front and rear lens caps, storage bag.

Had to choose the size that would benefit me the most. In the end, it was the 62mm set.
That would be the largest size based on my current lens selection.
Have a few smaller lenses and have the solution for that.
Get the 18 piece filter ring adapter set from K&F Concept.
(Made from the same aerospace grade aluminum alloy).
The perfect companion to this set.

All filters and caps are made of aerospace grade aluminum alloy.
The edges have non-slip teeth machined into the sides for a better grip when turning.
The CPL and UV filters are clearly printed on the side without the grooves (in bright white letters). The
CPL filter is slightly thicker than the UV filter because it has an adjustable ring.
Perfect threading of the entire four parts.
The optical CPL and UV glass both have a nano coating that makes them waterproof and oil resistant.
Even when I painted a nice big oily fingerprint on the glass, it was quick to clean.

The filter caps are available in K&F colors.
Black with an orange stripe.
The top cap also has an orange logo.

Storage.
When not in use, the filter set is very compact at about 0.75 inches thick.
Place in the drawstring storage pouch.
A dark gray to black soft bag with an orange drawstring with plastic ends.
Fits easily in a pocket or fits in an equipment bag.

Overall.
Attaching and removing the filters from my lens went smoothly.
Both filters can be used at the same time for outdoor shots.
As I said, no vignettes or dark corners.
The circular polarizer worked perfectly. Just rotate it until the glare is removed.
See photos of the bird bath.
This will go permanently in my gear bag. Recommended.
Hope this was helpful.

Most of my lenses are professional quality glass, which means they cost a small fortune. So it's very important to me that the filters I use don't compromise image quality or sharpness - I pay a premium price for that with the lenses I choose. I also want the glass to be well protected from scratches and dust, so at least one UV filter is a required part of my kit.

This is not an expensive model, but it is an excellent filter set that is on par with the best I have used and costs more than $80 for a UV filter. I have another brand that has served me well in UV, but I wanted to add a CPL filter and I was also hoping the coatings on this set would be better. I've included photos straight from the camera (just a few quick test shots) to show how clear the glass is and how much contrast and clarity this set offers.

The set comes with caps for both sides of the filters. You can choose not to use either filter and be sure it is well protected by the metal caps. They can also serve as lens caps for the filter set, which is handy, and I'm thinking about using them as such since dust gets under the lens cap that comes with the lens.

I found the filters very easy to clean and they don't seem to attract dust like my other filters. The cat had the audacity to rub its snotty nose and furry body against the lens when I was trying to get a shot. I didn't notice any vignetting in any area for a 70-200mm lens. Without the CPL filter, photos in RAW tend to be a bit washed out and this filter corrected that very well. They screwed on easily to my lens and are lightweight, which is also nice. The filter they replaced was not nearly as nice in either aspect and cost almost as much as the entire set just for UV.

I thought the advertising was spot on regarding the product and don't feel the need to add such details here. There are also some other really great reviews that show the product itself. Hopefully this review includes some helpful details about the filters on the lens and sample photos with the kit available. If you are looking for a great filter with UV and CPL, this is a great option.

I bought these to use with a Sigma 30mm f1.4 for portrait and landscape work.

As an amateur, I try to keep costs down, and since I already had several K&F filters, these seemed like a no-brainer.

They come in a very convenient bag that is well padded and has multiple pockets. Each filter comes packaged separately to protect them during shipping.

The glass in each filter is nice and clean and free of imperfections, and the thread was nice and smooth when attached (no grinding or incorrect threading).

The image quality doesn't seem to be affected, there is any extra tint or color cast when you use the filters.

They also came with a cleaning tool, which was a nice addition.

Overall, they are impressive for the price.

Pros
- cheap
- good optics
- great performance
- free cleaning tool

Disadvantages
- does not apply

Full disclosure: I received this filter system at a significantly reduced cost in return for my unbiased review.

I just purchased a new Canon RF 100-400 lens that has pretty good glass but is not L quality. Although I have a good black and white CPL filter that matches this lens, I have never been very happy with the color cast. I have tried other K&F Concept lenses and was very impressed with the neutral color cast. So I decided to give this polarizer kit a try.

I really like the technology in this kit. This kit comes as a compact sandwich with machined metal caps front and back. All caps and filters are clearly marked with the filter size. There is a small storage bag to protect the filters and your other stuff when you throw them in your bag.

I previously tried another K & F filter and while I was very impressed with the glass, I was much less impressed with the machined aluminum frame. Unlike the previous filters, these attach easily to my lenses and don't bind. In practice, the knurling on the filters makes removal very easy and in the case of the CPL, the adjustment is very smooth. There is noticeable resistance, but no hint of binding or freedom of 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 produces virtually no color cast at all. When held up to a white background, I can't tell the difference between filtered and unfiltered white. I don't usually use UV filters because most of my lenses have better front elements than any filter I own, but with the RF100-400, I'll probably leave the UV filter on the lens since it doesn't have the same quality coatings as my other lenses.

The CPL is fairly thick, but not so thick that I will worry about vignetting since I use these mostly with medium to long telephoto lenses. All CPLs affect color to some degree. Depending on the polarization and angle of the sun, they usually darken the sky and change the color of the water, sometimes dramatically, so with a CPL it is difficult to determine what color cast may be present. Using the same test on a white background, I can see a slight cast against the adjacent white background that seems to have a somewhat brownish cast, but could simply be the result of light loss from the CPL. In test photos, I could not see any perceptible cast at all. It's close enough to neutral that I don't think it will have much effect on color correction in post.

All in all, really nice filters and pretty good value for the money. Recommended.

I've been a photographer for years and a pro for some, but in all that time I've never come across a nicer filter presentation or polarizer. The filters come between two end caps, both precision machined from aluminum. There is no plastic here, nor any flaws or shortcuts in the machining process. I got these 49mm filters for a Leica. If ever there was an accessory kit that matches the feel and sense of this camera brand, this is it. I was, to put it bluntly, blown away.

While the UV filter seems to be every bit what I would expect from such a filter, which is mostly a lens protector with no image loss, I have no way to test such filters here. I can test the polarizer as this is a simple home test. It is very simple: take a picture of your monitor with the polarizer set to both minimum and maximum. Please look at the images that should be part of this evaluation to see the results.

Note that the test image shows the zones from 0 to 10. I set the camera to just clamp on 10 and run the 0 - 6 as you want to absolutely test this filter. The method is to see how many of the 8's, 9's and 10's are allowed through the filter at maximum polarization. Average filters, if the test is done correctly, will even show some leaks below 8. This filter completely filtered out not only the 8s and 9s, but also the 10s. I have never seen such a level of performance.

The pictures show the test pattern with the polarizer set to minimum (really zero), partially on, and fully on. You can see part of the monitor aperture fully because it is at a slightly different angle than the screen, so it is filtered out at a slightly different rotation angle.

It's one thing to create an excellent presentation, but it's another to have filters that work at a level that fits that presentation. These filters do. From now on, I'll shop this brand first when I need filters or photo accessories.

Very nice standard filter set consisting of a UV filter (clear) and a CPL filter. The two filters come assembled and have a threaded metal lens cap on each end.

These are ultra-thin filters that are less likely to cause problems like vignetting at the edges. Very well made, with machined aluminum construction on both the filters and the lens caps.

The CPL filter is a bit darker than what I'm used to, so it's better for outdoor daylight shooting than indoor.

The UV filter is the best I've ever used, crystal clear with no bluing or other artifacts - perfect, 100% clear. I always keep the UV lens on my camera lens for protection since it is so clear. Works well with stacking additional filters.

The threads all work flawlessly and the CPL makes for smooth rotation adjustment.

Great deal on this starter filter set.

*Photos do not show the UV filter as it was on my camera at the time.

I'm relatively new to photography, so I'll leave it to others to deal with the technical aspects of these filters. They worked great for me on a recent shoot at the beach. As you can see, the CPL reduced glare when shooting directly into the sun and water, but 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 as well. It has a nice, compact size that will easily fit in your camera bag. A small cloth pouch is included for protection. I am very pleased with these filters and I suspect you will be too.

My PC card reader could not read the SDXC card from my camera (possibly a hardware or driver error), so I bought a cable to connect the camera directly to the PC. Works fine and is long enough (1.5m) to reach the USB3 port on the back of the PC! ! Great value for money as Nikon version expensive. I then decided to buy "extras" (including filters) to get the postage and ended up with this set of 3 (ND, circular polarizing and UV) filters and a compatible Wi-Fi remote shutter release (also bargain). Arrived on time and everything works great! CHECK THE SIZE OF YOUR LENS BEFORE BUYING AS I BOUGHT THIS FOR MY MULTIPURPOSE LENS AND A DIFFERENT SIZE IS NEEDED FOR MY 35MM OR 70-300MM LENSES.

It's great to have that. They also blend well with the lens cover. The quality is impressive. I have it for my Sigma 16mm Sigma lens and the Sirui anamorphic lens, both are 67mm for my Panasonic BGH1 micro 4/3. I then switch back and forth between them depending on the shoot. So far it has been a good experience, especially with the CPL whose presence is more obvious. I leave the UV to protect tens on the outside as well as the CPL. Product of good quality.
