37mm CPL Filter True Color Circular Polarizers Filter with 28 Multi-Layer Coatings for Camera Lens Nano-X Series

I had been looking for a new circular polarizing filter for my camera when this opened up. This filter comes from a very reputable company, who I've gotten several other filters and accessories from before, and had great results. The lens that I use most often is a Nikon 18-200 zoom. This filter fit my lens perfectly and I didn't see any vignetting at any of the focal lengths. It is very well made with high quality optical glass and has 28 layers of MRC nanometer coatings to eliminate 99.9% of the glare and polarized light and allow crisp, sharp color through. The only downside, I found it a little stiff to rotate the front. But, hopefully this will loosen up over time. I have been using this now for about 4 weeks and have taken 100-150 photos with this filter. I feel it works really well and have gotten beautiful results. The price is also excellent for this quality. I highly recommend this CPL filter.

I've been using this with my Canon 18-150mm EF-M lens, and it took my shots from okay to wow. Nothing else to say, if you want better images during those hazy and sunny days, I found this has made a big difference. Thanks.

I have used Hoya filters for a long time, so it was a bit of a stretch for me to try something different. I was able to score this filter through the vine program, so I figured why not give it a try?
First off, the polarizer is well built. I had a Tiffen polarizer that would spin loosely, but this one feels solid. it is also a little heavier than what the other filter I have. The glass seems to have a nice clear tinting and has a noticeable effect on my pictures. It does what I expect a polarizer to do- brings out color on a nice sunny day and reduce glare. So far, I love it!

I used this filter on a recent vacation to Savannah GA and I was pleasantly surprised at the results.

This filter from what I can tell really does bring out more actual color from the surrounding area as you can see from these HDR photos I took with my Canon.

I have a lot of different filters but feel I will keep this on my lens most of the time going forward at this point.

A little stiff but still good for the price

A quality filter that is on par with my others. A bit stiff. All CPLs are tricky.
No problem with construction materials or very nice storage case, but as has been mentioned, it's stiffer than my other polarizers which makes it easy to accidentally unscrew it rather then simply realign it if you turn in the wrong direction!
CPLs are tricky and none are perfect - I guess it's just physics. For reflection removal, it works very well in the right circumstances (some angles to the sun work better than others). My chief complaint, and it's common to all of them, is how they affect color... a little extra saturation is nice, but they tend to emphasize the yellow and blue portions of the spectrum, sometimes creating odd gradations to the blue skies, or a slightly unnatural warm glow to the greenery. This one has those issues as well... but when used in a complementary angle to the sun, this filter provides a "mostly neutral" color and does not seem to suffer any resolution degradation.

As I said, this one matches up with the best of mine, so it deserves 4 or 5 stars. I've rounding down just because the stuffiness of the ring could cause some grief.

Sorry, these aren't professional photos, just things taken around the house, but they illustrate the functionality of the filter: (assuming they show in the original order)

1. A GOBE filter and a K&F. There is a visual color cast difference... the GOBE is biased a bit toward yellow/green, whereas the K&F is a more neutral gray with perhaps a tinge of magenta, possibly to help compensate for the polarizing effects?

2. A pool at right-angle to the sun with the polarizer attached but in the LEAST polarizing position.

3. A pool at right-angle to the sun with the polarizer attached but in the MOST polarizing position.

4. A window reflection with the polarizer attached but in the LEAST polarizing position.

5. A window reflection with the polarizer attached but in the MOST polarizing position.

6. A computer LED screen with the polarizer attached but in the LEAST polarizing position - colors should appear balanced... here they are a bit rich and perhaps a little blue, but this was in a VERY uncontrolled lighting situation so I consider the results to be fine.

7. A computer LED screen with the polarizer attached but in the LEAST polarizing position - screen should be very close to black

8. A harsh sun view of the forest with the polarizer attached but in the LEAST polarizing position.

9. A harsh sun view of the forest with the polarizer attached but in the MOST polarizing position. Sky is graduated a bit "off kilter" because it's hard to get a CPL aligned perfectly in bright sun and a wide angle can exacerbate the changing angles. Trees have more yellow in them, but the contrast is nice, so minor corrections in post could result in a pleasing outcome for a photo that would be otherwise flat.

Hope this helps!

I recently made the jump to Nikon mirrorless, so I've been slowly adding to my filter collection specifically for my one Z-mount lens... the 35mm 1.8s. All my other previous filters that I have purchased have been on the more budget side of the price range. After trying out this one, it's easy to see where the extra money goes when taking the jump to a higher quality brand/model.

For one, this filter is built so much better. The outer ring rotates incredibly smoothly with just the right amount of give. With some of my other filters, their rings rotates a bit too loosely so every little touch accidentally changes the polarization. With this filter, there seems to be far fewer accidents and I'm still able to control it with a single finger. Another thing this filter does well is it seems to be able to cut down a lot more glare. Many of my other filters seem to reach their limit a bit too quickly, and it takes a few attempts in order to hit that perfect spot on the outer ring. With the K&H filter, it's feel much easier to make those incremental adjustments.

For the most part, I only have one complaint. I'm not a huge fan of the case. It's designed well, and is more than capable when it comes to protecting the lens from dust and drops... but it's really, really big. It barely fits into my lens filter bag and it's not even close to the largest thread size that I own. It just has a bit too much wasted space imo, and I really wish they went with something a bit more form-fitting. Aside from that, it's a solid product, and I have no qualms giving it an easy 5/5 stars.

K&F Concept 72mm Polarizer does a good job of adding "sunglasses" to a shot. In other words it makes the sky bluer and reduces glare on glass and water. When I am shooting an exterior day event, in order to have my photos set apart from common mobile phone shots, this polarizer along with a slight black diffusion filter gives the shots a cinematic edge.

The filter reduces about 2 stops of light.

Note: The filter causes banding with extreme wide angle lenses like this 16mm (see photo). This is normal for all CPL filters, they are not meant for extreme wide lenses.

I performed a test using my Sony a7s with a Sony 16-35 lens. At 35mm there is less banding. (see photo) The important part to look at is the orange in the sky. It doesn't change. That is important, this K&F filter stays neutral to color which is important. Other CPL filters will tint the image.

As with all K&F products the build is excellent. It screws in effortlessly and has large knurls on the edge for an easy grip. This is an excellent filter to sport during a full sun day.

K&F concept used to be a second or third tier brand which solely focused on low-cost alternative camera products. It is no longer the case anymore. I have recently bought many of their products including tripod and lens filters. They are all working great and cost about 60% of the name brands.

This True color circular polarizer lens filter is no difference. It has over 28 layers of nanometer coatings which eliminates glare and offers waterproof. As U can see from my sample photos, all the glares were gone after rotating the filter. While I have not used this particular filter long enough to say it is truly scratch resistant, I can say with confidence that, based on my experience with other K&F nano costings filters, nano costing does offer certain level of scratch resistant.

What surprised me the most is the weight of this lens. It is noticeably light weight. In fact, this is the lightest weight lens filter I have ever owned considering this one is 82mm.

Caution: Because this is an ultra-thin filter, it is not easy to remove the filter. I highly encourage anyone who plans to get this filter also get a filter wrench kit.

Overall, I really like this polarizer lens. Highly Recommended.

This is a well constructed and very optically clear filter. I can see how it would help reduce glare and help bring out colors in a bright color situation.
