Light Lens Lab opened the pre-orders for the new Light Lens Lab 35mm f/1.4 Aspherical “11873” lens for M-mount (Double Aspherical AA).

Additional information on the new lens can be found here and on this new/updated page.

A new Titanium Limited Edition version was also introduced:

 
Pre-Order Notice for the Titanium Limited Edition version: pre-orders for the Titanium Grey Limited Edition will close on November 21st, 2025, at 12:00 a.m. EST.

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):

Specifications

• Focal Length: 35mm

• Optical Design: 9 elements in 5 groups (aspherical elements in groups 2 and 5)
• Minimum Focus Distance: 0.7 m (rangefinder-coupled)
• Aperture Range: f/1.4–f/16, 10 blades, preset diaphragm with half-stop lock settings
• Mount: Leica M-Mount
• Filter Thread: E46
• Lens Hood: Clip-on 12587
• Weight:
  • Aluminum: 278 g
  • Titanium: 300 g

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

LLL 에서 오랜만에 렌즈가 나왔군요.

그런데 프로토타입이 나온지 2년이 넘어버린 35.4 입니다..ㅋ

나왔었나…? 싶을정도로 2년이라면 시간이 꽤 지난건데,,

이번 렌즈는 출시가 꽤 오래걸렸네요.

라이카를 대놓고 카피해서 참 많이 욕 먹기도하고,

동시에 사랑받기? 도 하는 LLL 인데,

이번 35.4도 정품에 비교하면 별거 아니지만 카피로 생각하면 꽤 고가의 렌즈입니다.

예전에는 LLL 이 독보적인 제조사였는데,

이제는 중국 제조사들이 워낙 많아져서 과연 많은 주목을 받을 수 있을지 모르겠네요.
