The Samyang AF 24-70mm F2.8 FE is a fast standard zoom lens for Sony Alpha full-frame E-mount mirrorless cameras. It will also work with APS-C sensor cameras with an effective increase in focal length to 36-105mm due to the crop factor. It features 17 elements in 14 groups including 2 aspherical elements, a hybrid aspherical element, 3 HR elements and 3 ED elements. It has a near-circular 9 blade diaphragm which creates an attractive blur to the out-of-focus areas of the image, a minimum focusing distance of 0.35m (1.15ft), a stepping AF motor for fast and quiet autofocusing, a configurable Custom switch with two different modes, and it's also dust and moisture resistant. Weighing in at a whopping 1,027g / 36.2oz and measuring nearly 13cm in length, the aluminium alloy bodied Samyang AF 24-70mm F2.8 FE is certainly a substantial lens, rather dwarfing the Alpha A9 camera that we tested it with (especially with the supplied lens hood fitted), as shown in the photos below.
