Square Graduated Filter for Defined Horizons
This 100x150mm square filter provides a fixed 3-stop reduction across half the frame. It is built for landscape photographers who regularly shoot scenes with a clear, straight horizon line such as seascapes or mountain ranges. The hard graduation creates a distinct boundary between the darkened and clear areas. German B270 SCHOTT optical glass forms the substrate.
Consistent Transmission Under Bright Conditions
The 20 layers of nano-coating deliver a uniform transmission curve so the 3-stop density remains accurate across the spectrum. This prevents colour casts during long exposures in strong daylight. The coating also repels water and oil, keeping the surface clear when spray or mist hits the glass. Scratch resistance protects the optical layer during repeated field use.
Slides Into Standard 100mm Holder Systems
The filter matches the common 100mm width so it fits existing square filter holders without adapters. Its 150mm length allows vertical adjustment to align the graduation with the horizon. The hard edge demands precise placement; a misaligned transition cuts visibly across the frame. Photographers needing a softer blend for uneven terrain should choose a different graduation type.

Questions about this item
Does the 20-layer nano-coating on the Urth Plus+ filter affect heat buildup during long daylight exposures?
The coating is designed for consistent light transmission and easy cleaning, not thermal management; heat buildup depends on the camera and ambient conditions.
What filter holder system is required to use this 100x150mm square filter?
A standard 100mm filter holder with 100x150mm slots is needed; the filter itself has no built-in mounting threads.
Will the hard graduation line of this ND8 filter align cleanly with the horizon on older wide-angle lenses?
The hard edge is optimised for clearly defined horizons; ultra-wide lenses may curve the horizon, making the transition more visible.
