SEAGULL IRIS Graduated Neutral Density Filter ND8 40.5mm

The SEAGULL IRIS Graduated Neutral Density (GND) Filter is an essential tool for landscape and architectural photographers. Designed to balance exposure between bright skies and darker foregrounds, this filter helps you capture stunning, well-exposed images in high-contrast lighting conditions. With a density value of ND8 (3 stops), it reduces light transmission to 12.5%, allowing for longer exposures or wider apertures without overexposing highlights.

Advantages

This filter features a soft edge graduation, making it ideal for scenes with irregular horizons or where a seamless transition between the filtered and unfiltered areas is desired. The multi-coated optical glass ensures excellent color neutrality with no color cast, while the slim aluminum alloy frame minimizes vignetting on wide-angle lenses. Additionally, the filter is water and oil repellent, as well as anti-scratch, ensuring durability and easy cleaning in the field.
