Lightweight 20 mm ultra-wide prime for travel and video

Panasonic Lumix S 20mm F2.5

Panasonic introduces the LUMIX S 20 mm F2.5, a compact full-frame L-Mount prime lens designed for photographers and video creators who want an ultra-wide perspective without adding much size or weight to their camera setup.

With a focal length of 20 mm, the lens gives photographers plenty of room to work with the surroundings in the frame. This makes it well suited to landscapes, architecture and interiors, as well as travel and street photography where the environment is an important part of the image. The wide perspective is also useful for video, particularly when working in confined spaces or when both the subject and surroundings need to remain visible.

Despite its wide field of view, the LUMIX S 20 mm F2.5 measures approximately 40.9 mm in length and weighs around 142 g. Paired with a compact full-frame camera such as the LUMIX S9, it creates a small setup for everyday photography, travel and handheld video.
The F2.5 maximum aperture provides additional flexibility in lower light and gives photographers more control over background separation than a typical compact kit zoom. A minimum focusing distance of 18 cm also makes it possible to work close to the subject while retaining the wide surroundings in the composition.

The optical construction consists of 11 elements in nine groups, including three aspherical elements and three ED elements. The lens is designed to provide natural rendering across the frame, while focus breathing suppression helps maintain a consistent angle of view during focus transitions in video.

For operation, the LUMIX S 20mm F2.5 includes a customizable focus ring, a Lens Fn button and an AF/MF switch. Functions such as Crop Zoom can be assigned to the Fn button and autofocus is designed to operate quickly and quietly for both stills and video.

The lens has dust-, splash- and freeze-resistant construction and a fluorine coating on the front element to make water droplets, fingerprints and dirt easier to remove. It accepts 62 mm filters.

The new lens will start to ship in October 2026.
