Urth 75x100mm Square Soft Graduated ND4 2-Stop Lens Filter Plus+

SKU CH-7R50-M3TM1

A 75x100mm square soft graduated ND4 filter darkens skies by two stops for balanced landscape exposures

  • German B270 SCHOTT glass ensures superior light transmission for detailed images
  • 20-layer nano-coating repels water oil and scratches for easier cleaning
  • Soft graduated ND4 design balances exposure by blocking 2 f-stops at one end fading to clear
  • 75x100mm square format fits standard filter holders for versatile landscape use
  • Controlled exposures blend foreground and background light naturally for dynamic results

Professional Landscape Filter

The Urth 75x100mm Square Soft Graduated ND4 2-Stop Lens Filter Plus+ is built for landscape photographers who need to balance bright skies against darker foregrounds in a single frame. Its soft graduation transitions smoothly across the 75x100mm glass, making it suitable for horizons with uneven lines such as mountains or trees. Buyers who want a hard-edge transition or a circular screw-in format will not find that here.

Optical Construction and Transmission

German SCHOTT B270 optical glass provides the substrate, while a 20-layer nano-coating reduces reflections and repels water, oil and scratches for easier cleaning. The coating maintains high light transmission so detail remains crisp across both the darkened and clear zones. No thermal, noise or power specifications apply to this passive optical accessory.

Graduated Density Effect

The filter blocks 2 f-stops at its densest edge and fades to zero density at the opposite end, allowing controlled exposures without a visible seam in the image. This lets you retain highlight detail in the sky while preserving shadow information in the foreground. No bundled software, pouches or adapter rings are mentioned in the supplied data.

Questions about this item

How do I fit the 75x100mm square filter into my holder?

Slide the filter into the square slot of a compatible 100mm filter holder until it seats fully; the soft graduation must sit with the darker half covering the bright sky.

What cleaning does the 20-layer nano-coating need over time?

Wipe the SCHOTT B270 glass with a microfibre cloth and lens fluid; the coating resists water, oil and scratches so routine cleaning stays easy.

Where does the 2-stop density limit appear during long exposures?

The ND4 section blocks exactly two f-stops, so extremely bright skies may still clip highlights if the scene dynamic range exceeds that reduction.
