Great little circular polarizing filter. It’s low profile enough not to interfere with the gimbal shutdown action. It removes glare from very bright highlights or reflections without affecting image quality or color tones. If you have larger hands, it will likely be difficult to spin the filter as I have smaller nimble hands and felt it was hard but also impossible to do without getting your finger in the shot. Make sure to set up the filter before you hit record. Additionally, adjusting the polarizer causes the gimbal to wiggle, and in my case, I triggered a gimbal reset twice. Not a huge problem or a detraction from the filter but worth mentioning. Overall, it does exactly as promised, and if you have other neutral density filters or struggle with glare on some shots, it could be worth your coin. * Bonus: it came with a tempered glass screen protector; it went on without a hitch!

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.

This circular polarizing filter worked unexpectedly well to remove unwanted reflections and glare. Images were clear and colors appeared much richer. When using the polarizing filter, images are a little darker, so always shoot RAW for professional results and easy editing. By rotating the filter, the effect of the polarizing filter was visible in the viewfinder, which made composing my shots very easy. The build quality seems good and it feels pretty sturdy and well made, but it's not a 5-star CPL filter. Rotating the filter wasn't smooth or easy. Overall, it's not perfect, but it's good value for money and is a great CPL filter for long exposures.

I purchased this 82mm circular polarizing filter to use with both my Sigme 24-70 f/2.8 E mount and my Canon 24-70 f/2.8L II lenses. It's just a perfect polarizer for these versatile zooms.

The lens is extremely well made and the circular effect is smooth as silk when attached to the lens. The high-quality multi-coating ensures details in photos and videos without artefacts or haze and ensures excellent focus accuracy.

Polarizing filters have many uses, including deepening the color enhancements of skies and landscapes, especially in bright light conditions. In addition, the circular settings can be used to shoot through windows clearly and without reflection, and to take pictures or videos through water. For example, this filter can be used to capture perfect images of Koi (Japanese Colorful Carp) in a pond without light bouncing off the water's surface. There are other uses as well.

To operate, all that is required is to point a camera at the subject and rotate the outer plane of the filter until the desired effect is visible through the viewfinder... or on a screen. Easy peasy.

I own a number of K&F filters of various types including UV, ND and diffusers. I trust the company's products. This is excellent value for money compared to much more expensive polarizing filters such as those from B+W and Hoya while offering virtually equivalent performance. Fantastic!

It's an unequivocally high FIVE STARS from me, along with my honest and very warm recommendation. Improve your photography and vlogging! get this!

The circular polarizing filter does its job of not reflecting water, windows, etc. very reliably. The filter can be easily placed on the lens and a lens cap is included. Otherwise, the quality of the image fortunately does not change. Ultimately, it can be said that the filter is really unbeatable for this price.

I really like the circular polarizing filter. The ND filters are a bonus as they add motion blur and can achieve faster shutter speeds.

This is a two in one variable ND and circular polarizing filter setup. Very smart setup and avoids having to screw on more filters. Both are variable/adjustable individually with the small handles.

The quality of the glass is exceptional. Highly recommend.

The filter is very well packaged and makes a high-quality impression. I've only been able to test it so far. It simply screws onto the lens and is easy to use.
