The Sekor AF 80mm f/2.8 D lens is equipped with an auto/manual focus ring that allows fast one-touch selection of auto or manual focus mode. The lens barrel cover is made of turned aluminum treated with black alumite. The rubberized focusing ring makes manual focusing fast and easy. This standard lens for the 645 format has a field of view approximating natural human sight and works well in a wide range of applications for close or distant subjects. The Sekor AF 80mm f/2.8 D utilizes a 16 bit CPU that allows easy firmware upgrading, finer lens characteristic correction and faster, more reliable communication between the lens, camera body and digital back.
