Panasonic has announced that its Leica DG Vario-Summilux 10-25mm F1.7 ASPH lens - first teased at Photokina 2018 - will be available for purchase in July. Panasonic is marketing the 10-25mm, which in full-frame terms is equivalent to 20-50mm on a Micro Four Thirds body, as a single lens that covers five commonly used equivalent focal lengths: 20, 24, 28, 35 and 50mm.
The lens features a total of 17 elements, including aspherical, ED and UHR glass. The lens uses a stepping motor to provide fast, quiet focus. It has a nine-blade aperture and minimum focus distance of 28cm (11"). The lens isn't as large or as heavy as one would expect, and is very well-built and fully weather-sealed. It's the first Panasonic Micro Four Thirds lens with a focus clutch and a clickless aperture ring is also provided.
The 10-25mm was very much designed with video in mind, with minimal focus breathing, 'seamless' iris control for smooth exposure changes and linear focus response.
The Panasonic Leica DG 10-25mm F1.7 ASPH will be available in July for $1799/£1799.
