Description — Panasonic 12mm f/1.4 ASPH.
The Panasonic Leica DG Summilux 12mm f/1.4 ASPH. is a wide-angle prime lens built specifically for the Micro Four Thirds mirrorless camera system. Its f/1.4 maximum aperture makes it one of the faster options available in this focal length and format, enabling photographers to work in lower light without immediately reaching for higher ISO settings. At 12mm, the lens delivers a wide perspective well-suited to landscapes, interiors, street scenes, and architectural subjects.
The lens accommodates both autofocus and manual focus, giving shooters the flexibility to switch between modes as their subject or style demands. Weighing 335g, it is a manageable size for a fast prime in this category. The 62mm filter thread provides straightforward compatibility with standard filter accessories.
It is worth noting that this lens has no built-in image stabilization, so in-body stabilization on the camera body will need to handle any shake compensation. For Micro Four Thirds shooters looking for a dedicated, fast wide-angle prime for both photo and video applications, this lens covers the key bases.
