This Leica-branded ultra-fast Panasonic zoom matches the performance of most prime lenses in its focal length range and can therefore replace several lenses. A normal-to-short-telephoto zoom, it is a perfect documentary and travel lens for still photography as well as video creation. It is tack sharp at all focal lengths and apertures, and extremely well corrected against optical aberrations. It also perfectly complements the Leica DG Vario-Summilux 10-25mm F1.7 ASPH wide angle to normal zoom. Intuitive manual aperture and focus control rings round off this unique photo/video zoom lens.
