NEEWER 52mm Variable ND2–ND32 CPL filter

This variable neutral density and circular polariser combo from NEEWER lets photographers control exposure and reflections in bright conditions, helping to capture motion blur and richer skies while shooting outdoors. The 52 mm 2-in-1 filter reduces light by 1 to 5 stops according to the manufacturer and also provides polarising action to cut glare from water and glass, useful for landscape, long exposure and travel photography.

Key Points

The filter combines variable ND and CPL functions in one unit, so you can set the desired density and then rotate the outer ring to adjust polarisation without swapping accessories. The design aims to minimise the dark X cross effect that sometimes appears in variable ND filters when used on wide-angle lenses. Built for field use, it includes water-repellent and scratch-resistant nano coatings to reduce reflections and repel oils and moisture. Note that the front cap for this 52 mm filter should be 55 mm according to the manufacturer.

Benefits

Having ND and polarising functions in a single filter saves time when conditions change quickly, because there is no need to change filters between long exposures and glare control. The multi-coated HD glass lowers flare and ghosting, which helps retain contrast and colour fidelity when shooting backlit scenes or reflective surfaces. The engraved markings on the aluminium frame make it easier to set and repeat exposure reductions with precision, while the slim outer profile is intended to help reduce the risk of vignetting on many lenses.

Usage Recommendations

Before attaching, confirm your lens has a 52 mm thread; this is normally stamped near the front element along with the diameter symbol. When using the variable ND at stronger settings, check for any potential dark cross on very wide-angle focal lengths, although the filter is designed to mitigate this effect. Rotate the polariser ring slowly to find the point of maximum glare reduction, and combine moderate ND values with small apertures if you need longer shutter speeds for creative motion blur. Consider keeping a lens hood in place for extra protection from stray light and to reduce the chance of flare when shooting into the sun.

Note that the manufacturer indicates the variable ND range and the anti-crossing measures, and results may vary depending on lens focal length and camera sensor size.
