The Light Lens Lab 35mm f/1.4 Aspherical “11873” lens for M-mount was initially prototyped in 2023 and reviewed by Leica Society International. The lens has been refined with upgraded aspherical and high-refractive ED elements, improved alignment, and optimized performance for modern high-megapixel sensors. Here are the details (previous coverage of LLL lenses can be found here):

Additional information
A prototype of the 35mm f/1.4 Aspherical “11873” was first completed in 2023 and submitted to Leica Society International for in-depth testing and review. Based on their valuable feedback, we decided to postpone its release to make significant improvements to both the optical design and quality control process. The review of the first prototype of the 35mm f/1.4 Aspherical “11873” has been published by Leica Society International.
Please note that during the review of the 35mm f/1.4 Aspherical “11873,” the lens tested was our first prototype. Over the past two years, we have implemented several key changes to optimize performance for modern high-megapixel sensors. Insights from another optical project—soon to be announced—contributed to the final prototype of the 35mm f/1.4 Aspherical “11873.” After testing the final iteration of the 35mm f/1.4 Aspherical “11873,” we are satisfied and confident in moving forward with production.
- Titanium edition available for a limited time only: pre-orders for the Titanium Limited Edition will end on November 21st, 2025.
- Use of ED/Achromatic element and Lanthanide element: effectively reducing distortion, diffraction, and chromatic aberrations. Retains the legendary controlled “glow” characteristic at f/1.4.
- In-house production: all mechanical and optical components are designed, manufactured, and assembled entirely in-house.
- Changes to Aspherical Element Production: Transition from the use of a ground and polished method to a modern moulded and polished method. This change is due to the implementation of moulded aspherical elements, which enhance precision and optical consistency.
- New ED and Achromatic Element: Introduced a high-refractive low-dispersion and Achromatic Element alongside the new aspherical element to reduce distortion, diffraction, and chromatic aberration. At the same time, it maintains the legendary character and characteristics through the use of Lanthanide elements.
- Enhanced Quality Control: Improved assembly precision and element spacing—particularly between aspherical and spherical groups—to optimize alignment and image quality. The rear element has been slightly extended for better optical performance, while maintaining full compatibility with M-mount and adapted camera systems.
- New Optical Standard: Due to the high-performance aspect of 35mm f/1.4 Aspherical “11873.” The lens represents both a tribute to legendary lens design and characteristics and the foundation for our new high-performance optics series.
- Refinements of ASPH Element Production: Improve overall performance, minimize aberrations, and reduce diffraction.
- Use of Aviation Grade Aluminum and Titanium Alloy: For long-term usage with durability as priority
