Overview

The Neewer NW Series S 49mm Variable ND2-ND32 and CPL Filter combines two essential photographic tools into a single, slim unit. The variable neutral density element lets you dial in between 1 and 5 stops of light reduction using laser-etched markings on the CNC-machined aluminum frame, while an independent rotation controls the circular polarizer for cutting reflections off water, glass, and other shiny surfaces. This dual-function design means fewer filters to carry, fewer thread-on swaps in the field, and no stacking that could degrade image quality or cause vignetting.

Optical performance is supported by HD glass with 30 layers of nano coating applied to both sides, bringing reflectivity below 0.1% to combat flare and ghosting. The coatings also provide water, oil, dust, and scratch resistance, helping the filter hold up over time. Neewer's self-locking mechanism addresses the well-known dark-cross artifact that plagues many variable ND filters on wide-angle lenses, making this a practical choice for shooters who frequently work at shorter focal lengths. The ultra-slim frame keeps the overall profile low, though users should note that a 52mm lens cap or hood is required due to the slightly larger front diameter.

Key Features

【Variable ND & CPL Filter】After adjusting the ND filter and then rotating the frame, you can realize the functions of the ND filter and the CPL filter simultaneously. This 2 in 1 filter kit allows you to shoot under bright lighting conditions to capture motion blur images. It reduces reflections and glare from shiny objects like water or glass. The variable neutral density filter reduces 1–5 stops of light

【No Dark Cross Shadow】To solve the well known vignetting issue with variable ND filters when used on wide angle lenses, the NEEWER filter set uses self locking technology to ensure that there will be no dark cross shadow or vignetting when shooting with wide angle lens

【HD Optical Glass with Multiple Resistant Coatings】 With high quality HD optical glass and 30 layers of nano coatings on the both side of the filters, the reflectivity can reach less than 0.1% to reduce flare and ghosting. Protect the filter from water, oil, dust, and scratches

【Aircraft Grade Aluminum Alloy Frame】 Made of CNC machined aluminum alloy, the non slip texture of the frame makes it easy to install and remove the filter. Laser etched marks can be precisely controlled from the minimum (ND2) to the maximum (ND32) of light reduction. Featuring ultra slim design, the front diameter is larger than the back diameter of this filter. Note: For this 49mm ND filter, the lens cap/hood (Sold Sperately) should be 52mm.

【Compatibility】 Compatible with all lenses with a 49mm thread size. Please confirm your lens thread size before purchasing. The thread size is marked on the front or side of your lens, next to a "Ф" (diameter) symbol

Pros & Cons

👍 Pros

Combines variable ND and CPL into a single filter, reducing the need to carry and swap multiple filters
30-layer nano coating on both sides minimizes flare, ghosting, and repels water, oil, and dust
Self-locking design eliminates the dark cross artifact common in variable ND filters on wide-angle lenses
CNC-machined aluminum frame with knurled texture makes installation and removal easy even in the field
Ultra-slim profile reduces the risk of vignetting at wider focal lengths

👎 Cons

Requires a 52mm lens cap or hood instead of the standard 49mm, which means purchasing an additional accessory
Maximum light reduction of 5 stops (ND32) may not be enough for extremely bright conditions or very long daytime exposures
Variable ND filters can introduce slight color shifts at higher density settings compared to fixed ND filters

Frequently Asked Questions

Can I adjust the ND and CPL effects independently on this filter?

Yes. You first set the variable ND level (ND2 to ND32) and then rotate the outer frame to control the CPL polarization effect, so both can be dialed in separately.

Will this filter cause vignetting or a dark X-pattern on wide-angle lenses?

Neewer uses a self-locking design specifically to prevent the dark cross shadow and vignetting that many variable ND filters produce on wide-angle lenses.

What size lens cap do I need when this filter is attached?

Because the front diameter is larger than the rear thread, you need a 52mm lens cap or hood when this 49mm filter is mounted.

How many stops of light reduction does this filter provide?

The variable ND range covers 1 to 5 stops (ND2 through ND32), adjustable via the laser-etched markings on the frame.
