Marumi 100x150mm Reverse Graduated ND16 (1.2) Square Filter

Sunrise-sunset control

The reverse graduated ND16 reduces light by four stops with the darkest band centred in the middle of the frame, fading toward the top edge. This density profile matches the bright horizon line typical of sunrise and sunset compositions. The 100x150mm square format fits standard filter holders used by landscape photographers. It is not suited for scenes where the brightest area sits at the very top of the frame.

Schott B270 glass with multi-coating

High-definition Schott B270 glass forms the substrate, and both surfaces receive a double-side coating. The coating cuts reflection, resists scratches, repels water and oil, and reduces static build-up that attracts dust. Together these layers keep the optical path clean during repeated field use and simplify wiping between shots. No additional accessories or software are included in the package.

Square drop-in design

The filter measures 100mm wide by 150mm long and slides into a compatible holder without threads or rotating mounts. This square profile allows vertical shift to align the graduated transition precisely with the horizon. The rigid glass construction resists flexing when inserted or removed, and the coated surfaces withstand normal cleaning pressure. It requires a separate holder system and is not a screw-on circular filter.
