Filtrocam Pompei 100mm Magnetic Filter Holder Master Kit

Pompei is the Master kit built on Filtrocam's 1.1mm slim glass, and the thin section is the reason it exists. On a genuinely wide lens the stack in front of the element is what puts dark corners in the frame, so every filter here is cut at 1.1mm to keep the holder clear of the field of view.

The filter set is complete rather than a starting point: an ND64 at six stops and an ND1000 at ten stops for solid density, a soft GND0.9 and a soft GND1.2 for two strengths of sky-to-ground transition, and a reverse GND0.9 for the specific case of a sun sitting on the horizon, where the brightest band is at the horizon and not at the top of the sky. A rotating magnetic CPL holder carries all of it, adapters cover 67, 72, 77, and 82mm fronts, and every piece swaps magnetically in a second.
