Leica DG Summilux 15mm f/1.7 ASPH.

The Panasonic Leica DG Summilux 15mm f/1.7 ASPH. is a fast wide-angle prime lens designed for Micro Four Thirds mirrorless cameras, offering a 30mm equivalent focal length with a bright f/1.7 maximum aperture. The optical design incorporates three aspherical elements to minimize distortion and spherical aberration, delivering sharp and clear imagery across the frame. A Nano Surface Coating reduces lens flare and ghosting while maintaining contrast and color fidelity for high-quality stills and video recording.

The lens features an internal focusing system with a stepping AF motor that ensures fast, quiet, and smooth autofocus performance suitable for both photography and videography. An intuitive manual aperture ring and dedicated MF/AF switch on the metal barrel provide direct control over exposure and focus method, while the seven-blade rounded diaphragm contributes to pleasing bokeh quality.
