Urth 39mm Variable ND2 32 + ¼ Black Mist Filter Pro

The Urth 39mm Variable ND2 32 + ¼ Black Mist Filter Pro combines two essential photographic tools in a single high-quality optical filter. This professional-grade filter features a variable neutral density (ND) component with a density range from ND2 to ND32, allowing precise control over light transmission across 5 stops. The integrated ¼ Black Mist element creates subtle diffusion effects that soften highlights, reduce harsh contrast, and produce cinematic flare characteristics while maintaining image sharpness.

Constructed with premium optical glass featuring 16-layer multi-coating technology, this filter minimizes reflections, ghosting, and color casts while providing exceptional light transmission. The slim aluminum frame measures 39mm in diameter with a thickness of approximately 4.5mm, designed to prevent vignetting on wide-angle lenses. The filter features a smooth rotating mechanism for adjusting the ND density with precise click-free operation.

The hydrophobic and oleophobic coating on both surfaces repels water, oil, and fingerprints while facilitating easy cleaning. This filter is compatible with all 39mm threaded lenses and maintains accurate color reproduction across the visible spectrum. The variable ND function enables creative exposure control for achieving motion blur effects in bright conditions, while the black mist component adds atmospheric quality to portraits, landscapes, and cinematic footage.

The filter construction includes brass mounting threads with precise machining for secure attachment and durability. Optical performance is maintained across temperature variations from -10°C to 60°C without degradation of coating integrity. The filter weighs approximately 25g, contributing minimal additional weight to lens setups. This professional optical accessory is engineered for photographers and videographers seeking reliable exposure control and creative diffusion effects in a single, durable filter solution.
