The Light Lens Lab 50mm f/1.9 “Rigid-ZS6” is the newest addition to the Rigid Series, combining the classic 50mm f/1.9 “Super-Six” optical formula (6 elements in 4 groups, double-Gaussian design with full-frame 135 coverage) with the proven mechanical platform of the existing 50mm f/2 Rigid lens to deliver the original’s expressive bokeh and classical color rendering while boosting center sharpness for modern digital sensors. It is offered in two versions: the standard Rigid-ZS6 and a low-contrast Rigid-ZS6* (marked with an asterisk on the front ring) that provides greater highlight/shadow detail and a more film-like tonal response based on community feedback. The lens features an f/1.9 maximum aperture with a preset diaphragm and half-stop clicks, a compact build measuring just 45 mm long × 54 mm in diameter and weighing approximately 263 g, a brass outer barrel with aluminum/brass internals, M-mount quick-change bayonet, 0.7 m to infinity focus range, E39 filter thread, and compatibility with an optional A42 clip-on hood.

Dimensions & Weight
The 50mm f/1.9 “Rigid-ZS6” is a reinterpretation of the original “Super-Six” optical formula, paired with the established mechanical platform of the 50mm f/2 “Rigid.” It is designed to preserve the unique rendering characteristics of the original lens while improving usability and performance on modern digital systems.
The “Rigid” Series continues our research into classic optical formulas, adapted into a unified mechanical platform. Following the 50mm f/2 “Rigid” and “Rigid-SPII,” this release further expands the system. Ongoing developments include additional formulas such as the 50mm f/1.9 “S5” and 50mm f/2 “Apochromat.”
