The ZUIKO DIGITAL ED 14-35mm f/2.0 SWD, which covers a zoom range equivalent to 28mm to 70mm on a 35mm camera lens is the world's first standard zoom lens to feature a large f/2.0 aperture. Boasting industry-leading imaging performance, this lens is a worthy addition to the Olympus Super High Grade (SHG) series of lenses. Together with the ED 7-14mm f/4.0, ED 35-100mm f/2.0 and ED 90-250mm f/2.8 lenses, this lens completes Olympus' series of professional zoom lenses with fixed F-values
