Panasonic Lumix S 100mm ƒ/2.8 Macro Photography Lens with L-Mount

Panasonic's photography lens portfolio is split between two mount systems: Micro Four Thirds, shared with OM System under the consortium standard, and L Mount, developed as part of the L-Mount Alliance with Leica and Sigma. The Lumix G line covers the Micro Four Thirds range, including pro-tier Leica DG Vario-Elmarit and Vario-Elmar zooms designed in collaboration with Leica and certified to that brand's optical standards. On the larger-sensor side, the Lumix S line for L Mount includes the S Pro range, with weather-sealed primes and constant-aperture zooms such as the S Pro 50mm f/1.4 and 24-70mm f/2.8, alongside more compact S series options.

The lens roadmap is shaped in part by the L-Mount Alliance, which allows Panasonic L-mount bodies to use lenses from Leica and Sigma without adapters. This shared mount approach gives Panasonic users access to a substantially broader optical catalog than the company alone would produce, while Panasonic's first-party lenses tend to focus on hybrid stills-and-video performance characteristics such as suppressed focus breathing and silent autofocus, aligned with the company's strong video-camera positioning.
