Leica DG Summilux 15mm f/1.7 ASPH. The Panasonic 30mm equivalent wide-angle lens is designed for Micro Four Thirds mirrorless cameras. As a result of its bright maximum aperture of f/1.7, it is also highly useful when working in low-light conditions. It also provides greater control over the focus position for shallow depth of field and selective focus techniques. The manual aperture ring also provides intuitive control over aperture selection. Focusing is fast, quiet, and smooth with an internal focusing system with a stepping AF motor. A three aspherical element optical design results in sharper imagery and better overall clarity with less distortion and spherical aberration. Furthermore, the use of Nano Surface Coating reduces lens flare and ghosting for enhanced contrast and color neutrality in photos and movies.
It offers a 30mm equivalent focal length and is designed for Micro Four Thirds mirrorless cameras.
It is useful to have an aperture of f/1.7 to control the depth of field, especially when working in difficult lighting conditions.
The combination of a stepping AF motor with an internal focusing system results in fast, smooth, and precise focusing that is well-suited to still photography and movie recording.
A trio of aspherical elements produces sharper, clearer images by reducing spherical aberration and distortion.
Surface reflections are minimalized by a Nano Surface Coating to improve contrast, color fidelity, as well as reducing lens flare and ghosting.
A diaphragm with seven blades contributes to bokeh quality.
An aperture ring and a dedicated MF/AF switch make for a more intuitive, direct operation of the lens barrel.
