A Tribute to an Optical Legend 
The mid-20th century British "Super Six" optical design needs no introduction. The Super Six 2-inch f/1.9 stands as one of the most legendary standard-focal-length lenses in the realm of painterly optics. In its era, it represented the absolute pinnacle of balancing extreme resolving power with dream-like bokeh. The unique "3D Pop" it delivers wide open remains just as highly coveted today as it was decades ago. Driven by pure passion, DK-Optic has flawlessly paid homage to this masterpiece, combining its vintage soul with the extreme precision of modern industrial manufacturing.

Pure Optical Recreation 
We have engineered a 1:1 true-to-original restoration without any modern optical compromises or clinical "additives." We strictly adhered to the classic 6-elements-in-4-groups structural variation that made this historical design so famous.

Signature Rendering & Character 
Rejecting the sterile, dry perfection of modern lenses. Wide open at f/1.9, the Chiaro 2-inch delivers mesmerizing 3D spatial separation (subject isolation). The in-focus areas maintain astonishing sharpness, while the out-of-focus areas rapidly melt away into a signature, highly painterly bokeh. As you stop down the aperture, the image rapidly transitions, revealing exceptional contrast and high resolving power.

Cinematic-Grade Artisanal Construction 
Leveraging our high-end cinema lens production capabilities, every mechanical and optical component is designed and hand-assembled in our bespoke optical workshop—from the CNC 5-axis machining of core brass components to the grinding of decades-old New Old Stock (NOS) optical glass.

Silver Chrome Edition: 
The main exterior barrel is crafted from high-strength 7075 aerospace-grade aluminum to significantly reduce weight. The core focusing helicoid and aperture mechanics are machined from aerospace-grade brass, providing an unmatched, buttery-smooth tactile feel.
