Konica Minolta 28-70mm f/2.8 G AF

(From Konica Minolta lens literature) This lens allows you to use a maximum aperture of f/2.8 at any focal length from 28 to 70mm. It also has a nine-bladed circular aperture that produces rounded, more natural background highlights, in addition to a moving mask that blocks flare-causing light at any focal length.
