The black Panasonic LUMIX G Leica DG Summilux 15mm f/1.7 ASPH. Lens is a prime wide-angle lens designed for Micro Four Thirds sensors. Its 35mm-equivalent focal length is 30mm, making it ideally suited for everyday shooting applications. The fast f/1.7 maximum aperture benefits working in low-light conditions and also avails greater control over the focus position for shallow depth of field and selective focus techniques. Intuitive control over the aperture selection is also possible through the use of the manual aperture ring. In regard to focus, an internal focusing system with a stepping AF motor promotes fast, quiet, and smooth performance.
The optical design incorporates three aspherical elements to reduce distortion and spherical aberration for sharper imagery with greater overall clarity. Additionally, a Nano Surface Coating has been applied to lens elements to suppress lens flare and ghosting for more contrast-rich, color neutral photos and movies.
