Nikon Series E 28mm f2.8 lens mount_Contax RF Tap the rear button toThe Nikon Series E 28mm f2. 8 is a very compact wide angle lens for Nikon F mount. Series E lenses are Nikon's "cheaper" manual focus lenses, usually with older designs this one's based on the pre AI 28mm and more lightweight construction. Not a bad little lens, though! Light dust, smooth focusing, excellent cosmetic condition.
