Flexible and lightweight, an ideal lens for your everyday moments
A compact zoom lens for easy daily use. It offers a wide focal length range – from 18 mm for wide-angle shots to 40 mm, perfect for natural portraits, allowing you to freely capture various photos.
The smallest and lightest interchangeable lens in the world
Always by your side, wherever you go. With a retractable zoom system, the overall length and weight of the lens have been reduced to less than half that of a conventional zoom lens designed for the LUMIX S series. Even when paired with the LUMIX S9, it remains extremely lightweight – only 641 g.
S-R1840 lens structure
The optimized configuration consists of 8 elements arranged in 7 groups, including 2 ASPH, 2 ED, and 1 UHR lenses, to minimize aberrations and ensure impeccable resolution.

・In lenses that can compensate for distortion, the horizontal axis indicates the distance from the corrected image center.
Dust, splash, and freeze-resistant construction
Thanks to its dust and splash-resistant construction, this lens is designed for shooting in the toughest conditions and allows photography at temperatures as low as –10 °C. The front lens is coated with a fluorine coating that prevents oily dirt from sticking.
