Urth

Urth 39mm Circular Variable ND2-32 Lens Filter Plus+

SKU CH-583T-E0NNP

A 39 mm variable ND filter giving 1 to 5 stops of light reduction using German SCHOTT B270 glass with 20 nano-coating layers

  • 1 to 5 f-stops for creative exposure control
  • German SCHOTT B270 glass for optical clarity
  • 20-layer nano-coating resists water, oil and scratches
  • Ultra-slim rim prevents vignetting on wide-angle lenses
  • Double-threaded design allows stacking or cap attachment

What this filter does

The Urth 39mm Circular Variable ND2-32 Lens Filter Plus+ reduces incoming light by one to five f-stops. Photographers and videographers use it to keep wider apertures or slower shutter speeds in bright or changing conditions without overexposing the frame.

Limits of the variable range

The filter covers ND2 to ND32, so it cannot reach the deeper density needed for very long daylight exposures or extremely wide apertures in harsh sun. At the strongest settings some wide-angle lenses may show a subtle cross-polarisation pattern.

Upgrade from fixed ND filters

Replaces a set of single-density screw-in filters, letting you dial the exact stop you need without swapping glass. The jump is worth it when you shoot video or fast-changing light and need continuous adjustment rather than stepping between fixed strengths.

Questions about this item

How do I pick the right filter size for my lens?

Match the 39 mm thread diameter printed on your lens barrel or in its specifications; this filter only fits lenses with that exact thread size.

What does the ND2-32 rating actually do when I am shooting?

It lets you dial between 1 and 5 stops of light reduction so you can open the aperture wider or slow the shutter without over-exposing the frame.

How does the double-threaded mount affect stacking or lens caps?

The front thread accepts a 39 mm cap or another filter while the rear thread locks onto your lens, so you can stack or protect the glass without removing the ND.
