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