NEEWER 2 Pack ND0.9/1.8 Square ND Filter 4x5.65 in - Precise Light

In this review of the NEEWER 2 Pack ND0.9/1.8 Square ND Filter the bottom line is simple: this set is for photographers and video shooters who need reliable, neutral, cinema-grade light reduction for matte box workflows. The reviewer found the 4in x 5.65in size fits mini matte boxes from NEEWER, Tilta and SmallRig, and the dual strengths (3 stops and 6 stops) deliver predictable control over shutter speed and aperture when shooting in bright conditions. Color neutrality and durable coatings stood out as the single biggest reasons to buy.

Key Features

• Matte box compatibility: Designed for NEEWER matte boxes and compatible with Tilta and SmallRig mini matte box frames for straightforward mounting.
• Two-stop options: The ND0.9 provides 3 stops and ND1.8 provides 6 stops to tame exposure and enable longer shutter speeds or wider apertures in bright light.
• Proper size for cinema use: The 4in x 5.65in square format gives ample coverage for many cinema lenses and filter holders used on small rigs.
• HD optical glass: High-quality optical glass preserves sharpness for 4K and 8K capture without introducing noticeable color cast.
• Multi nano coatings: Thirty layers of coatings on both sides resist scratches, oil and fingerprints while reducing reflections to improve contrast.
• Lightweight and portable: A slim profile adds minimal bulk to a setup and the included pouch protects the filters when transporting gear.

Who It's For

The NEEWER 2 Pack ND set is best for independent filmmakers, run-and-gun videographers, and photographers who use small matte boxes or filter frames and need predictable exposure control under bright sunlight. It suits users who want neutral color performance for 4K or 8K work and value durable coatings that stand up to on-location handling.

Those who should look elsewhere are shooters who require variable ND for stepless adjustments or users who need circular screw-in filters for still-photography lenses without a square holder. Studio-only shooters who never work in bright outdoor conditions may also find a separate solution more fitting.

Pros & Cons

Pros

• Neutral color reproduction preserves accurate color balance with no visible color cast in normal use.
• Durable multi nano coatings resist fingerprints, oil and scratches, keeping optics clear on shoots.
• Two distinct densities (3 and 6 stops) provide practical light control for motion blur and depth of field management.
• Slim, lightweight design and protective pouch make these filters easy to transport and mount.

Cons

• Fixed-stop ND set lacks the convenience of a variable ND when gradual adjustment is needed.
• Square format requires a compatible matte box or holder rather than direct lens mounting.
