Wide 24mm equivalent for Micro Four Thirds

This Panasonic Leica DG Summilux 12mm f/1.4 ASPH. lens delivers a 24mm field of view on Micro Four Thirds cameras. The bright f/1.4 maximum aperture suits low-light shooting and gives strong control over depth of field. Its all-metal, weather-resistant build handles demanding environments. A quiet autofocus motor and manual focus switch support both stills and video work.

Optical performance at wide apertures

Two aspherical elements, two ultra extra-low dispersion elements and one extra-low dispersion element correct spherical and chromatic aberrations across the frame. Sharpness and clarity remain high from centre to edge even at f/1.4. The nine-blade rounded diaphragm produces smooth background rendition. The lens maintains consistent rendering when stopped down toward f/16.

Micro Four Thirds system constraints

The 12mm focal length covers the Micro Four Thirds image circle only; it does not fill larger sensor formats. Autofocus speed and accuracy depend on the camera body’s contrast-detection or phase-detection implementation. The f/1.4 to f/16 aperture range limits exposure control in extremely bright conditions without neutral density filtration. Weather resistance protects against splashes and dust but not immersion.
