The K&F Concept Circular Polarizer and Neutral Density Filter offers the convenience of two quality useful filters in one, at a reasonable price.
The neutral density filter provides between 2 to 6 stops of light reduction, more than enough when wanting to slow your shutter speed for video or specific type of photography, like waterfalls.
Similarly, the circular polarizer removes glare and enhances color and contrast.
Although the filter did not come with instructions, using it is easy, and the outer rim of the filter is clearly marked to indicate the amount of light reduction. Turning clockwise changes ND levels, and counter clockwise is the circular polarizer.
The rotation of both the ND filter and circular polarizer is smooth and even, and the frame, which is made of aluminum alloy, is well-machined and screws easily into the lens. Overall, the filter appears very well made and it even comes in a very nice (leather looking) carrying case.
Bottom line, this is a very useful and convenient filter to have in your kit. Content creators of all types, video and photos, will appreciate the ability to reduce light for video and different types of photography, and increase contrast and color vibrancy.
Highly recommended!

use the neutral density filter for my nature photography and landscape photography. Especially when photographing rivers, lakes or waterfalls, this filter, thanks to its variable darkening from ND2 - ND64, offers an extension of the shutter speed, which creates motion blur, which looks very nice with watercourses. In addition to the ND filter, there is a second filter function, a CPL polarization filter. This is very practical when photographing water, lakes and streams, as reflections can be compensated for at the same time. The processing quality is very good, even with maximum darkening of ND64, the unwanted X effect does not occur. The inexpensive filter shows good imaging properties in all areas and is ideal for ambitious and creative amateur photographers

Out of the gate the first thing you’ll notice is the build quality on this filter. It it feels really solid in your hand, there are no loose parts and has a good weight to it. I like how it has little grip extenders that you can grab a hold of to turn the filter. As the filter does need a little bit of pressure to turn it, it’s nice to have these so your fingers don’t slip. I like how it has hard stops on the ND filter so you don’t accidentally turn it too far, which can mess up your image really quick regardless of what brand filter you’re using.

The metal, variable ND filter helps with long exposures and manages to reduce a few steps. For recordings that are not shot in direct sunlight, it is sufficient, for example, to smooth out water. The processing is top and you can get nice pictures with it. Including cleaning cloth - and super case in which the ND filter is not damaged. (If you don't know: the diameter of your lens is written directly on your lens). The filter is also perfect for adhering to the 180掳 shutter rule when filming with DSLR /DSLM. We are convinced! Simply screw on the ND filter - done! The protective cap from the lens also fits on it :)

Really excellent build quality. It turns out to be robust, with excellent materials. Super recommended, also because a CPL in combo with a variable ND is really affordable at this price.

I've always liked k&f for their affordable camera gear, but this time they've outdone themselves! Beautiful packaging and presentation, which really make it feel more premium! The filter works like a sharm with my Nikon d5300 and the 18-35mm wide angle lens.. Does darken the sides when it's all the way, but for me that's not a problem.. If you're looking for a 2-in-1 CPL & ND filter, this one won't disappoint !

The CPL+ND filter does exactly what it promises. It helps reduce glare on windows, protects the camera lens, and adds some enhancement through saturation. Compared to some of my other CPL filters, they have slightly more saturation improvements than other filters. I hardly experienced any vignetting. All in all a good price for an ND filter & CPL filter.

This CPL+ND filter shows material and function quality. It comes with a nice box protector and some information. It screws easily into the camera. This filter is for my everyday and travel camera so I am always looking to travel minimalist and this is giving me that.

This is just incredible. I'm using it with my Sony A7iii and the 24mm f1.4 G Master lens. Will update later with some waterfall shots. Definitely recommend this!
