Flexible and light, the ideal lens for your daily moments
Compact zoom lens for easy everyday use. It offers a range of focal lengths, from 18mm for wide-angle shots to 40mm, for taking portraits with a natural perspective, giving you the flexibility to enjoy taking a variety of snapshots.
The world's smallest and lightest zoom lens
Always by your side, wherever you go. By adopting a retractable zoom system, the overall length and weight of the lens have been reduced to less than half that of the conventional zoom lens for the LUMIX S Series. Even when combined with the LUMIX S9, it is still super lightweight, at a mere 641g.
Dust, splash and freeze-resistant design
This lens is designed to keep shooting in the toughest conditions thanks to its dust- and splash-resistant construction and allowing you to shoot in temperatures as low as -10°C. The fluorine coating applied to the front lens prevents the sticking of oil-based dirt.
Perfect for portraits with a natural perspective
Offering outstanding sharpness and resolution throughout the entire zoom range, this is an ideal lens for the LUMIX full-frame system, and provides creative opportunities without compromise. The optimized configuration has 8 elements in 7 groups, including 3 ASPH, 2 ED and 1 UHR lenses to minimize aberrations and ensure superb resolution.
Ideal for video recording
The lens offers fast, accurate autofocus and smooth aperture changes, critical for the modern content creator, allowing you to record beautiful 4K video and stills without disturbing your subject.
