K&F Concept CPL + Variable ND Filter ND2-ND32 Nano X 72mm

K&F Concept CPL + Variable ND Filter ND2-ND32 Nano X 72mm | Control reflections and light in one filter

Bright light can force you into a faster shutter speed than you want, while reflections on water or glass can distract from the subject. This K&F Concept filter combines a circular polariser (CPL) with a variable ND filter, so you can address both issues with one filter on a 72mm lens thread. The ND2-ND32 range lets you reduce the light reaching the camera by one to five stops; that gives you room to use a slower shutter speed in daylight, for example when you want movement in a stream to appear softer. The CPL function helps reduce reflections and glare, which can make a difference when photographing water, windows or other reflective surfaces. It suits photographers and filmmakers who want to manage exposure and reflections without changing between separate filters. Its usefulness depends on the scene: polarisation varies with the angle of the light, and the filter won't remove every reflection.

Where the combination helps

For a moving-water scene, the ND range gives you more freedom to lengthen the exposure while keeping your chosen aperture and ISO. At ND32, the filter reduces light by five stops; as a simple example, an exposure of 1/125 second could become about 1/4 second at the same aperture and ISO. For a reflective surface, the CPL function addresses glare instead. These are distinct effects in one filter, so choose the adjustment for the problem you’re trying to solve.
