This lens is currently the widest zoom lens available for full frame mirrorless cameras. Designed primarily for travel photography, we have managed to compress the size to the smallest in its class, less than 9.1 cm (3.6 in.) long and only 496 g (1.1 lb.). The 130° (10mm) to 102° (18mm) angle of view provides flexibility for photographers to compose landscape or architecture photos with ease. The aperture blade system is carefully designed to produce the best sun-star renderings among all UWA lenses on the market.
