Hello Everyone,
With our continued commitment to the research and development of legacy and vintage optics, we are pleased to announce the upcoming release of the Light Lens Lab 50mm f/1.9 “Rigid-ZS6.”
This release also marks the continuation and expansion of the Light Lens Lab “Rigid” Project.
Prototype Illustration, final production verison will be revised in aestheic.
Product Overview
The 50mm f/1.9 “Rigid-ZS6” pays homage to the original 50mm f/1.9 “Super-Six” optical schematic and rendering characteristics, while integrating them into the proven mechanical platform of the 50mm f/2 “Rigid.” This combination merges a historically significant optical formula with a robust, field-tested mechanical design.
Prototype Illustration, final production verison will be revised in design.
We are also implementing design changes to the front ring, and here are several ideas for the revised design:
Key Features
-
Heritage Optical Design
Based on a classic double-Gaussian configuration, newly refined to preserve the distinctive “Super-Six” rendering—characterized by expressive bokeh and a classical colour signature.
-
Optimized for Digital Capture
The optical design retains characteristic aberration behaviour while improving relative center sharpness through optimization for modern digital sensors.

Dual Rendering Options
In response to community feedback regarding improvements and optimization, a Low Contrast (“*”) version will also be offered.
This variant preserves greater highlight and shadow detail, emphasizing the original “Super-Six” character with a more film-like tonal response.
The low-contrast version is identified by a “*” marking on the front ring.
-
Precision Mechanical Construction
Brass outer barrel construction paired with aluminum and brass internal components ensures durability, smooth operation, and long-term reliability.
-
In-House Manufacturing
All internal and external components are manufactured in-house, maintaining strict quality control across both optical and mechanical systems.

Introducing the “Rigid” Series
We are pleased to formally introduce the Light Lens Lab “Rigid” Series—a unified mechanical platform designed to house a range of historically significant optical formulas.
This initiative continues our research into classic optical designs by renowned legacy designers, internally referred to as the “ACDK” series, adapted into a standardized lens barrel architecture.
Following the release of the 50mm f/2 “Rigid” and 50mm f/2 “Rigid-SPII, the introduction of the 50mm f/1.9 “Rigid-Super-Six” marks the next phase of this project. Ongoing development includes additional optical formulas such as:
-
50mm f/1.9 “S5”
-
50mm f/2 “Apochromat.”
All are being engineered for integration within the 50mm f/2 “Rigid” mechanical platform.
