Description — Rokinon 12mm T2.2 CS NCS
The Rokinon 12mm T2.2 CS NCS MFT Lens is a prime wide-angle lens designed for the Micro Four Thirds mirrorless camera system. Built for shooters who prioritize manual control and cinematic exposure accuracy, it features a T2.2 maximum aperture — a T-stop rating that reflects real-world light transmission, making it a practical choice for video and hybrid shooting workflows. The 12mm focal length puts it firmly in wide-angle territory, opening up creative possibilities for architecture, interiors, landscapes, and cinematic wide shots.
At just 235g, it is a compact and lightweight lens that won't weigh down a rig or cause fatigue during extended shoots. The 67mm filter thread provides straightforward compatibility with standard circular filters. Focus is entirely manual, with no autofocus mechanism, giving filmmakers and photographers deliberate, hands-on control over their focus.
The lens mounts natively on Micro Four Thirds bodies, with no image stabilization on board — shooters requiring stabilization will need to lean on their camera body's IBIS or an external solution.
