  • Reduces light to 6.25% to maintain desired settings in harsh conditions
  • 20-layer nano-coated German SCHOTT glass ensures exceptional light transmission and image clarity
  • Ultra-slim rim design eliminates vignetting for optimal optics
  • Tough magnalium construction provides lasting resilience backed for life

Fixed ND16 for 37 mm threads

The Urth 37mm ND16 (4 Stop) Lens Filter Plus+ cuts four f-stops, reducing incoming light to 6.25 percent. Landscape photographers and videographers use it to keep wide apertures or slow shutter speeds in bright conditions without overexposing the frame.

37 mm thread limits vignetting control

The ultra-slim rim is engineered specifically for the 37 mm thread size to minimise vignetting on wide-angle lenses. Any step-up or step-down adapter adds thickness that can reintroduce corner shading, so the filter works best mounted directly on a native 37 mm front thread.

Replaces basic uncoated ND filters

Photographers moving from single-coated or uncoated neutral density filters gain 20-layer nano-coated German SCHOTT glass that resists water, oil and scratches while delivering a more consistent transmission curve. The jump is worth it when cleaner optics and easier cleaning matter for frequent outdoor use.
