Genustech Polarizer ND Variable Filter 82mm

This filter puts two controls in one piece of glass: a variable neutral density element for pulling exposure down across roughly 2 to 8 stops, and a circular polarizer for cutting reflections and haze and deepening color and tonal saturation. The two elements rotate independently, so density and polarization angle are set separately rather than fighting each other.

Genustech builds it from water white glass with HD laser-treated elements for color fidelity, with a front filter thread sized up to 86mm to keep the front element clear of vignetting, and includes a microfiber cloth and rotation extension handle for fine control on both photo and video work.
