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..

does it's job pretty well.

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.

No colour cast whatsoever, good build quality and very strong

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.

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.

Works well on my EF 70-200 lens. Recommended.

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.

Having worked my way up to photographic equipment that is weatherproof enough that it can withstand a downpour it is important to me that my filters are also weatherproof. I needed a CPL filter for a new lens and saw this one by K&F caught my eye and I ordered it.

I know K&F from their adapters, and I have previously tried a couple of their ND filters, but I had not come across their Nano-X range before.

This particular filter caught my eye for two main reasons. Firstly, it was listed as having both water and dust proof coatings, and secondly, it had 28 coatings which I assume are 14 per side.

The filter comes in a nicely designed case which holds it in place very firmly. The filter coatings are claimed to be waterproof, and I tested that claim out by running it under the tap and the water was nicely repelled. So far so good.

The filter screwed in okay to the lens with no unusually grungy feel to the threading. Once screwed on I tried rotating the outer ring of the filter and this is where I had an issue. It took much more effort to rotate it than I like. I had to tighten the filter onto the lens much more than usual to be able to rotate the outer ring without unscrewing the filter from the lens. It has loosened a little with use but is still stiffer than my personal preference.

The filter certainly does what else it is claimed to do, however. The true color is just that, true. No color shift at all and it is effective at reducing glare.

Overall, this is a filter that gives very good results and that makes it definitely worth trying if you don't mind a stiff outer ring. Some people do I know, but I prefer mine to be somewhat easier to rotate.
