This 24-70mm f/2.8 AF Zoom Lens for Sony E from Samyang delivers a wide-angle to short-telephoto angle of view and a bright maximum aperture throughout the entire zoom range. It can be used for diverse photos such as landscapes, portraits, and snaps. In particular, the optimum resolution is achieved through the optical design of 17 elements in 14 groups (2 ASP, 1 H-ASP, 3 HR, and 3 ED). The minimum focusing distance is just 13.8", ideal for images such as food on tables or portraits with exaggerated features. The lens features weather sealing at seven spots to protect it from light dust, rain, and snow and provide the ability to capture stunning images in less than perfect conditions. The 9-blade circular aperture contributes natural-looking bokeh and the beautiful starburst effect. The Custom Switch makes it easy to select functions including Aperture Control Mode MF Mode. A linear stepping motor allows a larger and heavier focus lens group to be controlled quietly and precisely. As the AF speed is properly controlled during video recording, wobbling is reduced and stable video recording is possible.
