Ultra-Compact Wide-Angle Prime Lens joins the LUMIX S Series alongside new firmware updates for the LUMIX S9, S1RII, S1II
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 exceptionally compact design, the new lens offers greater creative freedom for fullframe 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 fullframe 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 the bright F2.5 aperture, this enhances low-light performance and enables attractive background separation. This opens 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 centre 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 customisable Lens Fn button and control ring, enabling users to personalise 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 an 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 makes it easy to remove dirt, water droplets, and fingerprints from the surface.
The LUMIX S 20mm F2.5 joins the LUMIX S 40mm F2 lens released earlier in the year, further expanding Panasonic’s lineup of compact full-frame lenses and providing creators with an additional option that balances image quality and ease of use for capturing high-quality content every day.
The lens is priced at $849RRP and will be available in October from select photo specialists and consumer electronics retailers. Colour options are Black (S-S20GC-K) or Light Silver (S-S20GC-S).
