About & Disclaimer
L-Mount Lens Guide is an unofficial, community-maintained directory of lenses for the L-Mount lens mount system. It is a volunteer open-source project, built and maintained by photography enthusiasts, not by any camera or lens manufacturer.

What "L-Mount Alliance member" means on this site
Each lens entry is tagged as either an L-Mount Alliance member product or a third-party (non-Alliance) product:
- L-Mount Alliance member — the brand is a publicly listed member of the L-Mount Alliance (as of 2026: Leica, Panasonic, Sigma, Ernst Leitz Wetzlar, DJI, Astrodesign, Samyang, Blackmagic Design, Sirui, Viltrox, and Freefly). This reflects the brand’s membership status, not a per-lens certification.
- Third-party (non-Alliance) — the manufacturer is not an L-Mount Alliance member. Listing a lens here only means the manufacturer sells, or has announced, an L-Mount version of that lens. It is not a claim of official compatibility testing, certification, or endorsement by the L-Mount Alliance or any Alliance member. Third-party lenses may have compatibility limitations (autofocus behavior, firmware support, stabilization coordination, etc.) that differ from Alliance-member lenses — always check current compatibility notes from the lens manufacturer before purchasing.
Data accuracy
Lens specifications are compiled from publicly available manufacturer sources and community references. They may contain errors, omissions, or become outdated as products are updated or discontinued. Every lens entry lists its source links — always verify specifications against the manufacturer’s current published data before making a purchasing decision. If you spot an error, please open an issue or pull request. (the project repository)
Data collection is affected by a range of factors — for example, a manufacturer’s page may only publish a given specification (such as weight) for a different mount version of the same lens, and that figure can end up recorded here in error. As a result, some entries may be inaccurate or outright wrong. This project accepts no direct or indirect liability for any inaccuracies, omissions, or errors in the data. Some specifications are genuinely difficult to find published anywhere online — where that is the case, defer to the actual product rather than to this site.
