Panasonic officially announced the Leica DG Vario-Summilux 10-25mm F1.7 ASPH M 4/3 lens. Recently, a lot of unverified information has been published about the lens, both from insiders and from various online stores.
The Leica DG Vario-Summilux 10-25mm F1.7 ASPH. is suitable not only for stills shooting but also for video recording, to satisfy both professional photographers and videographers. The full-range F1.7 ASPH. high-speed aperture provides beautiful bokeh and high descriptiveness and covering a focusing distance from wide-angle to standard zoom range.
This lens functions as multiple fixed-focal-length lenses, providing the same or higher level of descriptiveness than a fixed focal-length lens can offer. Panasonic claims that the lens has extremely high optical performance and is suitable not only for photography but also for video. The lens is equipped with three aspherical lenses and four ED lenses (with extremely low dispersion). These lenses are effectively suppressed axial chromatic aberration and chromatic aberration of magnification, according to the manufacturer. Spherical aberrations and distortions are also said to be corrected by aspherical lenses.
Panasonic notes that the use of aspherical lenses and the optimal design of the optical scheme made it possible to create a lightweight compact lens. The company also claims that the optical design provides exceptional barycentric stability, which minimizes image shifts when scaling.
