Filtrocam Procida 100mm Magnetic Filter Holder Entry Kit

Procida is the entry point into Filtrocam's rectangular system: a rotating magnetic CPL filter holder that takes 100 x 150mm glass, sized for wide-angle work where a stacked screw-in setup starts to vignette. The glass in this kit is 1.1mm thick, the slim option in the line, which is exactly the point when a lens is wide enough that every millimeter in front of it shows up in the corners.

The kit covers the two filters a landscape shooter reaches for first: an ND64 for six stops of solid density and a GND0.9 graduated ND for pulling a bright sky down to meet the ground. A 90mm magnetic circular polarizer mounts behind the holder without cutting into the frame, and 67, 72, 77, and 82mm magnetic adapters cover most lens fronts. Everything swaps and removes magnetically in a second, and the glass carries multi-layer anti-reflection coating that is shock resistant, anti-dust, and oil-proof.
