In 2010, GL Optics ignited a revolution in the filmmaking industry. Faced with sky-high lens prices, creators craved a more accessible entry point. The Mk I, our inaugural offering, wasn't just a rehoused lens; it was a game-changer.

Gone were the limitations of off-the-shelf mechanics. We engineered our own iris drivers and helicoid focus systems, unlocking a coveted 300° focus throw. This meticulous precision offered filmmakers unparalleled control and accuracy for crucial focus pulling.

Focusing on precision: We upgraded the helicoid focus system for even smoother, more precise control. Additionally, we introduced the revolutionary interchangeable mount system, empowering filmmakers to swap mounts (PL, E, EF, Nikon) in the field with ease.

The Mk IV housing was a complete overhaul. We refined the focus driver and helicoid systems, achieving even smoother control and closer focus capabilities. We embraced modern materials and techniques, implementing tougher anodizing, laser engraving, and ink markings for a sleek and durable finish.

The Mk V wasn’t just a lens rehouse; it's a culmination of a decade of innovation and passion. We poured everything we learned into crafting this magnum opus, a housing that for us, sets the new standard for precision, performance, and aesthetics.
