Ultra-Compact Wide-Angle Prime Lens joins the LUMIX S Series
alongside new firmware updates for the LUMIX S9, S1RII, S1II

NEWARK, N.J., Sept. 16, 2026 /PRNewswire/ -- Panasonic is pleased to introduce the new LUMIX S 20mm F2.5 (S-S20), an interchangeable lens based on the L-Mount system standard. Combining an ultra-wide 20mm focal length with a bright F2.5 aperture in an exceptional compact design, the new lens offers greater creative freedom for full-frame LUMIX users.

Designed for creators on the go, the LUMIX S 20mm F2.5 delivers expansive perspectives while maintaining a compact and lightweight form factor. Particularly well suited to the LUMIX S9, it forms a highly portable full-frame system for daily photography, travel, street photography, landscapes, and video content creation.

The 20mm focal length offers a natural ultra-wide-angle perspective, capturing a greater sense of space and atmosphere without becoming excessively dramatic. Combined with its bright F2.5 aperture enhances low-light performance and enables attractive background separation, opening up creative possibilities beyond those typically achievable with a standard kit zoom lens at a similar focal length.

Despite its compact dimensions and weight of approximately 142g, the lens delivers high optical performance through an advanced design incorporating three aspherical lens elements. Sharp rendering is maintained from the center to the edges of the frame while effectively suppressing various aberrations, delivering clear and natural image quality across a wide range of shooting situations.

For video creators, the LUMIX S 20mm F2.5 suppresses focus breathing for natural-looking focus transitions during recording. Whether capturing everyday moments, social media content, or travel videos, creators can enjoy smooth and reliable still and video performance.

The lens also includes a customizable Lens Fn button and control ring**, enabling users to personalize operation according to their individual shooting style. In combination with the upcoming LUMIX S9 Firmware version 2.1, users, will be able to assign functions such as Crop Zoom directly to the Lens Fn button, providing intuitive control and enjoyable shooting experience.

Built for reliable use in challenging conditions, the LUMIX S 20mm F2.5 lens features a dust- and splash-resistant design* while a fluorine coating on the front lens element helps making it easy to remove dirt, water droplets, and fingerprints from the surface.

The introduction of the LUMIX S 20mm F2.5 further expands Panasonic's lineup of compact full-frame lenses, providing creators with an additional option that balances image quality and ease of use. Together with the LUMIX S9 and LUMIX ecosystem services, the new lens encourages daily usage and a practical and enjoyable experience for capturing high-quality content every day.
