Affordable stills and cine lens maker strengthens L-mount Alliance
Graphic: Leica Leica has announced that the L-Mount Alliance is growing. Chinese lens and accessory maker Sirui (pronounced "Sue-Ray") is joining the alliance, becoming the ninth company to do so. The addition of another lens maker means more options for those who use L-mount cameras. Sirui is perhaps best known for its reasonably priced anamorphic lenses, which offer cinematic looks at a much more affordable price than traditional options. The company already has a fairly healthy lineup of lenses in multiple series. That includes the relatively new Aurora series, which currently only features the Aurora 85mm F1.4, the company's first full-frame autofocus lens. More recently, Sirui launched the Vision Prime Series, a lineup of full-frame cine lenses. Outside of lenses, the company also makes a few tripods and lighting options. For its part, Sirui says it is "set to significantly enhance the L-Mount Alliance lens ecosystem." The lens maker already offers four L-mount lenses: two cine lenses and two anamorphic lenses. Joining the L-mount Alliance means that more are on the way, and, given what Sirui currently makes, it should add greater variety to the L-mount lineup. "Our aim is to introduce a broader range of outstanding, high-value L-mount lenses to the market," said Li Jie, Founder and CEO at Sirui Optical. Leica, Sigma, and Panasonic are current members of the L-mount Alliance producing L-mount lenses, but none of those offerings are anamorphic lenses. Plus, while there are options that work well for cinematography, none are dedicated cine lenses. Given that Blackmagic Design joined the alliance in 2023, it is likely a welcome addition to have the promise of more cine lenses on the way. The two companies didn't share any specific product announcements along with the reveal of the partnership, though, so only time will tell what will eventually be on the table. SIRUI joins the L-Mount Alliance and utilizes the L-Mount standard developed by Leica Camera AG in future product development Teaneck, March 20th, 2025. As a new member, SIRUI is the 9th company to join the L-Mount Alliance since the public announcement of the L-Mount standard at Photokina in 2018. The alliance consists of founding members Leica Camera AG, SIGMA, and Panasonic, as well as Ernst Leitz Wetzlar GmbH, DJI, ASTRODESIGN, SAMYANG Optics, and Blackmagic Design. This collaboration enables SIRUI to develop products with the L-Mount, which will present great benefits for a wide range of photo and video applications. The L-Mount was developed by Leica Camera AG with the aim of providing customers with a future-proof, flexible, robust, and precise bayonet mount that would fulfil even the most demanding photographic needs. Since its initial appearance, development of the L-Mount was continued by Leica as well as by its strategic partners. This led to significant improvements and an effectively new and more polished L-Mount technology, resulting in an ever-growing portfolio of cameras and lenses from all existing and new alliance partners. All lenses made for the different systems within the L-Mount Alliance can be used on all cameras without adapters and without any functional limitations – this illustrates one of the numerous benefits of the common bayonet. Valentino Di Leonardo, Managing Expert Technology & Licensing at Leica Camera AG: “The L-Mount Alliance stands for openness, innovation, and the highest quality in photography. By welcoming SIRUI as a new member, we are not only expanding our network with another strong partner but also reinforcing our commitment to diversity and fresh impulses within the ecosystem. SIRUI brings new perspectives and expertise to the Alliance, enriching the L-Mount system with forward-thinking approaches. Together, we aim to provide photographers and filmmakers with an even more comprehensive and flexible system that meets the highest standards.” Li Jie, Founder and CEO at SIRUI Optical: “SIRUI is a globally recognized brand in optical imaging, offering a diverse product lineup that includes optical lenses and photography and videography equipment. Our company operates with its headquarters in China and has subsidiaries in the United States, Germany, and Japan. With its in-house optical R&D and manufacturing facilities, SIRUI has established a fully integrated system encompassing research, production, and sales, with a distribution network spanning over 60 countries and regions worldwide. By leveraging its proprietary brand, independent technological innovations, vertically integrated supply chain, and cost advantages, SIRUI is set to significantly enhance the L-Mount Alliance lens ecosystem. Our aim is to introduce a broader range of outstanding, high-value L-mount lenses to the market.”
