Panasonic Leica DG Summilux 9mm f/1.7 ASPH Lens Bundle with 55mm UV Filter

Leica DG Summilux 9mm f/1.7 Overview

The Panasonic Leica DG Summilux 9mm f/1.7 ASPH is a Micro Four Thirds prime lens built for professionals and advanced amateurs. It delivers a 9mm ultra-wide angle view with a bright f/1.7 maximum aperture. The optical design uses twelve elements in nine groups, including two aspherical, two ED and one UHR lens to control aberrations. A bundled 55mm UV filter and microfiber cloth add front-element protection.

Build Integration and Handling

Weighing approximately 130g, the lens adds minimal mass to a Micro Four Thirds body and keeps the system highly mobile. Its dust- and splash-resistant construction supports shooting in adverse conditions. The focus ring offers both linear and non-linear response modes, while micro-step aperture control enables smooth exposure transitions during video recording. Focus breathing is suppressed for consistent framing when racking focus.

Ideal Users and Limitations

This lens suits creators who need a fast, wide prime for low-light stills and silent, breathing-controlled video on Micro Four Thirds cameras. Buyers requiring autofocus compatibility with other lens mounts should look elsewhere. Photographers who want zoom versatility or longer focal lengths will need a different optic. The fixed 9mm focal length and f/1.7 aperture define its creative envelope.
