49mm Circular Polarizer Lens Filter with Filter Cap Optical Glass Ultra Slim Polarizing CPL Filter with 24 Multi-Layer Coatings for Camera Lenses Nano-Dazzle Series

The amount of glare this can filter out is basically everything, whereas most CPL can only do a noticeable amount. I've held off on buying a filter for my largest 82mm lens due to cost, but this brand seems to do well punching above its weight and competing with my $400 CPL. As with my other expensive filters, the lines of the filter don't line up with the notches, so I can't really tell which way the filter is rotated from the front. I don't really need the cloth and lens cap, although I can imagine someone benefiting from it, but I don't know why it comes with a wrist strap. The photos are manually set to rotate 90° for the full polarizing effect.

The K&F Concept 82mm Circular Polarizer Lens Filter is a fantastic addition to any photographer's kit. It significantly reduces glare and reflections, ensuring vivid colors and improved contrast in your shots. The build quality is solid, and the ultra-thin design prevents vignetting. While it's a little more expensive than some alternatives, the multi-layer coatings make it worth the investment.

The K&F Concept 49mm Circular Polarizing Filter with Filter Cap Optical Glass Ultra Thin Polarizing CPL Polarizer Filter with 24 Multilayer Coatings for Camera Lens (D Series) is well made and feels like good quality. It's a great product for the money.

have been a fan of K&F Filters and many of their other photography products for some time and have come to appreciate the brand's consistency and quality. Most of my lenses live their lives with a K&F Concept UV protection filter on the front. I have sufficiently tested the transmittance and sharpness of K&F filters in the past that I now consider them a trusted brand. I am confident in their quality. And that's the point, right? Find a supplier you can trust to deliver exceptional quality. I use polarizing filters extensively, much more often than not. They are a multi-purpose filter that allows the user to add contrast and saturation, reduce glare and reflections, and to some extent, since they add neutral density, control exposure. There is little reason not to use them, except in low light situations. Another benefit of the 82mm size, and most sizes for that matter, is its cost advantage. The use of step-up rings allows it to accommodate a range of lenses that require a smaller filter size. This applies to filters of any size. In practice, the K&F Concept 82mm polarizing filter can be used on lenses with filter sizes from 77mm upwards, provided appropriate adjustment rings are used. You do not need to buy a separate polarizer for each of your lenses. The filter is solidly constructed from aircraft-grade aluminum and is typical of the high quality of K&F Concept filters in general. The damping of the outer ring is even and provides the necessary resistance to keep the adjustment securely in place. Since a CPL has no stop, when adjusting it it must be rotated in the same direction that you would attach it to avoid accidentally detaching the actual filter from the lens. K&F Concept uses AGC glass, formerly Asahi Glass Company, a Japanese company that is the largest glass manufacturer in the world. They also claim that there are 24 multi-layer anti-reflective coatings on each side of the glass, which are important for reducing internal lens reflections. In my testing, the filter lived up to the seller's claims. It polarizes light and the colors seemed "true," or at least to the extent inherent in the rendering capabilities of a digital sensor. This was affected by camera settings and the sharpening and dynamic range features introduced by the manufacturer. In other words, "True Colors" is subjective. Also, I did not notice any reduction in sharpness when using the filter. The physical properties of the filter are its relatively light weight, as well as the faceted chinas around the perimeter of the polarizing ring, which provide a better grip. I use an 82mm VND filter, which is 82mm in diameter, and the thread on the front of the filter, also 82mm, provides enough depth for the stacked filter to be securely attached. The K&F front lens cap that comes with the filter is on par in quality with any OEM lens cap I own. The clamping levers are easy to use, firmly spring loaded, and give a firm grip to the filter or the lens it is attached to. I also appreciate that the front threads on the CPL match those of the 82mm filter size, allowing the use of standard OEM accessories such as a lens protector. The filter comes with the lens cap, an adjustable lanyard, a high-quality microfiber lens cleaning cloth, and a plastic storage case. K&F Concept offers good value for money and doesn't cut corners.

It feels good quality as usual with the brand. In this case it comes with a cover to protect the filter itself and a strap to attach it to the camera. I didn't notice any deformation or artifacts affecting the image quality due to the filter. It fits perfectly and the roulette feels solid.

CPL filters are a must-have for any photographer. They reduce glare, intensify overall colors, especially of blue skies, and make landscape images pop. This filter is well made and does the job. The cap is a nice addition to the kit. Lens caps tend not to fit well on filters and can also be easily lost. Spare parts are always welcome.

Circular polarizers are great for landscape photography for two reasons. First, if any sky is included, the reflections from invisible water droplets in the air can be eliminated, increasing color saturation and contrast in the sky. Just dial in the effect you want. Second, if water is in the photo, annoying extraneous reflections can be greatly reduced or eliminated completely! The included lens cap, which fits over the filter, provides both a protective cover and a replacement for your 82mm lens — a nice bonus. Very nice polarizer!

I'm very happy with this circular polarizer. K&F is a reputable brand so it works well for more expensive equipment. My 82mm filter screwed onto one of my Canon 24-105 zooms with no problem. It did a good job of reducing reflections on initial testing. There may be some slight vignetting at the corners but I'll have to confirm that with more extensive testing with landscape photos. I was impressed with the packaging. It came in a hard plastic case with an extra lens cap (which I've never seen included with filters) and a vacuum sealed polishing cloth. No complaints and I've used some pretty cheaply made filters in the past.

This is a good quality filter that doesn't seem to affect image quality other than its intended purpose of polarizing light. Once attached to a lens, it rotates smoothly to achieve the correct polarization angle. The included case offers great protection, although it is a bit bulky. The matching lens cap protects the lens once attached to a lens. I'm not sure how the included strap is supposed to be used with the filter.

The polarizer works as expected, the metal ring material is lightweight and easily screws onto my lens. The lens cap helps me avoid accidentally touching the surface of the filter glass when attaching the filter. The cap is also good in case I accidentally misplace my original lens cap.
