Overview

The NEEWER 49mm HD Variable ND Filter gives photographers and videographers stepless control over light transmission from ND2 to ND32 — a range of 1 to 5 stops. This makes it straightforward to shoot with wider apertures in bright sunlight for shallow depth of field, or to slow shutter speeds for motion blur in video work, all without swapping between individual fixed-density filters. The filter is built around Japanese AGC optical glass, which is known for consistent clarity and minimal color cast, and its 30 layers of nano coating work to suppress reflections, ghosting, and flare that can degrade image quality.

Physically, the filter is built with an aircraft-grade aluminum alloy frame that keeps weight down while resisting cross-threading and wear. At just 7.4mm thick (excluding the mounting thread), the slim profile reduces the risk of vignetting on standard and moderate wide-angle lenses. The front ring rotates smoothly for on-the-fly density adjustment, which is especially useful during video recording when lighting conditions change. For photographers who need more than 5 stops of reduction, a stacking approach or a dedicated high-density fixed ND would be necessary, but for general-purpose exposure control the ND2–ND32 range covers the most common scenarios cleanly.

Key Features

【Variable ND2-ND32 Camera Lens Filters】 This 49mm variable camera lens filter features 5 stops of exposure brightness, from ND2, ND4, ND8, ND16 to ND32 (the numbers represent how much light enters the lens in terms of a fraction). Use this filter to gain more control over exposure and shutter speed when shooting rivers, waterfalls, light trails, etc

【No X cross dark spot】 With markers on the frame, rotate the filter to accurately adjust ND stop with ease. When mounted on wide angle lens, no need to worry about X cross dark spot. A 52mm lens cap is required to fit on the 49mm filter

【Multi Layer Nano Coated HD Optical Glass】 Made of premium Japanese AGC optical glass, the high definition ND filter delivers cinematic photo look without distorting image quality. The 30 layers of double sided Nano coatings, with 0.1% minimum light reflectivity, reduce flare and ghosting while protecting the filter against moisture, oil, dust, and scratches

【Professional Build】 The aircraft grade aluminum frame makes the filter lightweight. 0.37"/9.5mm thick (including thread, 0.29"/7.4mm thick excluding thread), this ultra slim filter helps avoid vignetting. Finished in black matte and CNC precisely machined, it is durable and has zero chance of being jammed on lens

【About its Compatibility】 This 49mm ND filter can only fit 49mm camera lens. Please confirm the filter thread size marked on your camera with the "Ф" (diameter) symbol before ordering. When mounted on camera, the ND filter also protects your camera lens from scratches. Protective case and cleaning cloth also included

Pros & Cons

👍 Pros

30-layer nano coating effectively reduces ghosting and lens flare in backlit situations.
Japanese AGC optical glass maintains sharpness and color neutrality across the density range.
Aircraft-grade aluminum alloy frame is durable yet lightweight on the lens.
Ultra-slim profile at 7.4mm helps prevent vignetting on most lenses.
Smooth rotation between ND2 and ND32 allows precise, stepless exposure adjustment.

👎 Cons

The 49mm thread size limits use to smaller lenses unless step-up rings are added.
Maximum density of ND32 (5 stops) may not be enough for very bright conditions or long daytime exposures.
Variable ND design can introduce slight color shifts at the extremes of its range.
No hard click stops, so repeating an exact density setting requires visual reference or an external meter.

Frequently Asked Questions

What density range does this variable ND filter cover?

It adjusts from ND2 to ND32, providing 1 to 5 stops of light reduction so you can control exposure across a wide range of lighting conditions.

Does this filter cause vignetting on wide-angle lenses?

The ultra-slim frame design (7.4mm excluding thread) is engineered to minimize vignetting, though extreme wide-angle focal lengths on crop or full-frame sensors may still show slight corner darkening.

What type of glass is used in this filter?

It uses Japanese AGC optical glass with 30 layers of nano coating to reduce reflections, ghosting, and flare while maintaining sharpness and color accuracy.

Will this filter produce the "X" cross pattern at higher densities?

Variable ND filters can exhibit a cross pattern near their maximum setting. This filter's ND2–ND32 range is conservative enough to keep that artifact to a minimum compared to wider-range variable NDs.

What lens thread size does this filter fit?

This is a 49mm filter. It threads directly onto any lens with a 49mm front filter thread.
