Panasonic Lumix 9mm f/1.7 ASPH Leica DG Summilux Lens

The Panasonic Lumix 9mm f/1.7 ASPH Leica DG Summilux is a wide-angle prime lens built for the Micro Four Thirds mirrorless system. At just 130g, it is a remarkably lightweight option for photographers who prioritize portability without sacrificing a fast maximum aperture. That f/1.7 maximum aperture sits at the brighter end of the wide-angle prime spectrum, making it well-suited for shooting in challenging lighting conditions or for achieving a shallower depth of field than slower alternatives in its focal length class.

The 9mm focal length places it firmly in ultra-wide territory for the Micro Four Thirds format, making it appealing for landscape, architecture, street, and environmental portrait work. It accepts 55mm filters, a convenient standard size that makes finding compatible accessories straightforward. The lens supports both autofocus and manual focus operation, giving shooters flexibility in how they work.

It is worth noting that the lens does not include optical image stabilization, so users will need to rely on in-body stabilization if their camera body provides it. Overall, this is a compact, fast, and capable ultra-wide prime for Micro Four Thirds shooters.
