It even comes with a cleaning cloth for the filter. The construction is top notch and the polarizer functions work.

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!

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. Photos taken with Nikon D3200 and Nikon AF-S Nikkor 18-300mm 1:3.5-5.6G ED 1st photo: without filter 2nd photo: with filter

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.

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.

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.

Ive ordered this CP filter for all of my lens sizes and am always impressed by this company's products! Not only does the filter fit and feel solid and well made, but the true color CP give impressive results! Great company to deal with too, excellent customer service and they actually listen to customers and impliment improvements..

The polarizing filter makes a solid impression, the thread runs cleanly and without scratching

The glass is first rate - the rim is very stiff and gets worse in the cold, and physically very difficult indeed to unscrew because the knurled rear part is slightly too small in external diameter for a good grip. You could end up unable to remove it quickly, so just as well it loses only the minimum amount of light. Good coating suppresses flare. Photo example shows use to dial down the light reflected off the sea maximum, leaving the sky/sun unaffected, but underexposed deliberately for the sun and clouds. Without the polariser the sea would be as bright as the sky.

Play Video As a photography enthusiast I recently got my hands on this 77mm polarizing filter and I have to say it exceeded my expectations! The HD optical glass used in the filter ensures sharp and clear images with vivid colors and high contrast. The circular polarizing filter (CPL) attaches easily to my 24-105 lens and I appreciate the fact that it doesn't add significant weight to my camera setup.
