Overview

The Benro Master Variable ND Filter in 72mm gives photographers and videographers a versatile tool for controlling exposure and depth of field without swapping between fixed-density filters. Its 1-to-9-stop variable range is among the widest available, making it practical for everything from opening up a fast lens in bright midday light to achieving smooth, long-exposure water and cloud effects. The B270 German Schott optical glass at its core is a high-quality substrate that maintains sharpness and minimizes chromatic distortion across the frame.

What sets this filter apart from many competitors is its dual-coating system — ULCA multi-coating paired with NANO WMC coating — which actively combats flare, ghosting, and the color shifts that can plague lesser variable ND designs. The CNC-machined matte black brass ring adds durability and a premium feel while ensuring the filter threads smoothly onto your lens and rotates evenly when adjusting density. For photographers who want a single, high-quality filter that can handle a broad range of lighting scenarios, the Benro Master is a compelling option.

Key Features

Fixed Min and Max Densities - Provides consistent and repeatable results

ULCA Multi-Coating - Decreases flare and significantly reduces chromatic aberration

NANO WMC Coating - Scratch-resistant multi-coating that repels water and oil making it easier to clean

Black Coated Glass Edge - Prevents internal reflections and decreases optical flare

CNC Matte Black Brass Ring - More resistant to side impacts, less likely to bind when placed onto a lens

Pros & Cons

👍 Pros

  • Wide 1–9 stop range covers everything from subtle light reduction to long-exposure effects in bright conditions
  • B270 German Schott glass delivers high optical clarity with minimal image degradation
  • Dual ULCA and NANO WMC coatings reduce flare, ghosting, and color shift
  • CNC brass ring resists cross-threading and provides smooth rotation for precise adjustments

👎 Cons

  • At 9 stops the vignetting and X-pattern common to variable NDs may become visible, especially on wide-angle lenses
  • 72mm size may require step-up rings for smaller lens threads, adding bulk
  • Higher price point compared to basic variable ND filters from budget brands
