The LIGHT LENS LAB 50mm f/1.5 Z21 is a special model that reconstructs the famous French lens, the Angenieux 50mm F1.5 Type S21, using modern optical technology and new materials. The "Z" in Z21 stands for the initials of the designer, Mr. Zhou, and is imbued with the desire to inherit the spirit of the developers who worked on the original S21.
This lens inherits the classic double Gauss configuration, but has been redesigned to pursue the distinctive appearance of the "S21." Its soft yet sharp depiction is reminiscent of the classic lenses of yesteryear. Furthermore, rather than simply pursuing high resolution, we focused on the essential values of photographic expression, such as "bokeh" and "beauty of aberrations."
While other companies eliminate aberrations, this lens deliberately leaves aberrations, and produces a "poetic light" that cannot be described by numbers alone; this was made possible through deep optical understanding and a bold artistic challenge.
The image circle is designed to be slightly larger than the original. Even with a 44 x 33 mm format image sensor, you can use it at close to medium distances without worrying about vignetting. *Slight vignetting may occur only when shooting at infinity.

LIGHT LENS LAB M-Mount 50mm F1.5 Z21 Prime Lens, Full-Frame (3-Year Manufacturer's Warranty), Leica M Compatible, Reproduction of the French Angenieux 50mm F1.5 Type S21 Lens, Manual Focus, Standard, Piano Black, Integrated Lens Hood
The LIGHT LENS LAB 50mm f/1.5 Z21 is a special model that reimagines the legendary French lens, the Angenieux 50mm F1.5 Type S21, using modern optical technology and new materials. The "Z" in Z21 stands for the initial letter of its designer, Zhou, and embodies the spirit of the engineers who created the original S21. This lens retains the classic double Gauss configuration while being newly redesigned to capture the distinctive appearance of the S21. Its soft, sharp rendering is truly reminiscent of the legendary lens of yesteryear. Furthermore, rather than simply pursuing high resolution, we focused on the essential values of photographic expression, such as "bokeh" and "beauty of aberration." While other companies eliminate aberrations, this lens deliberately retains aberrations, capturing a "poetic light" that cannot be expressed simply by numbers; this is the result of deep optical understanding and bold artistic challenges.
Classic looks and operation. Luxurious "Piano Black" finish. While the lens exterior emphasizes a classical atmosphere, we paid particular attention to the feel of the precise helicoid and aperture ring. This lens combines the traditional style of the historic "S21" with modern ease of use. The glossy "Piano Black" version, which requires advanced manufacturing techniques, offers a sleek, luxurious appearance that will enhance the joy and satisfaction of owning it. The Piano Black version is a rare model, limited to 600 pieces worldwide.
A fusion of the original's style and modern performance. Correction values were thoroughly analyzed using professional measuring equipment, faithfully reproducing the original's rendering characteristics obtained from historical documents and sample images. Meanwhile, optical performance is approximately 10% better than the original in the central 30% of the frame, from the center to the periphery.
High image quality achieved through new materials and a new design. The latest optical glass is used throughout, and the coating has been optimized using modern technology. While improving sharpness and contrast, it also provides images that make use of the unique soft tones and bokeh of the "S21." Peripheral illumination has also been slightly improved compared to the original, allowing for more natural peripheral images.
Larger image circle The image circle is designed to be slightly larger than the original. Even with a 44 x 33 mm format image sensor, you can use it at close to medium distances without worrying about vignetting. *Slight vignetting may occur only when shooting at infinity.

About LIGHT LENS LAB LIGHT LENS LAB is a manufacturer founded by Chinese investors. The project to recreate the original Summicron 35mm F2 started as a hobby, and became a hot topic after producing a product (8 lenses) that was as close as possible to the original, not only in terms of lens construction and materials used, but also in terms of imaging performance.
