Konica Hexanon AR 28mm 3.5f Wide Angle Lens in very good condition + Original leather case + Konica Metal Lens Hood for Hexanon 24mm 28mm Lenses (55mm) in very good condition. The Hexanon 28 mm / F3.5 was one of the first lenses to be developed for the new AR bayonet – for the old F bayonet no lenses with focal lengths shorter than 35 mm were available. The first variation was a preset lens without automatic aperture, all later variations had automatic aperture and an AE setting for automatic exposure control. The preset version has neither mechanisms for the actuation of aperture nor a largest aperture coupling between camera body and lens – with this lens, on all bodies with through-the-lens (TTL) metering, the metering must be done in stopped-down mode and the aperture has to be set manually on the lens prior to exposure. 28 mm became a very wide-spread standard focal length. These lenses were built over a long timespan in large quantities and have been developed and redesigned several times. Therefore, a lot of different variations of the lens do exist. Even the basic optical design has been altered several times – from originally 7 elements in 6 groups on the preset lens to 7 elements in 7 groups and finally to 5 elements in 5 groups. The lens, most so in the later 5 element variations, is quite small and light-weight, therefore well suited for Street and travel photography.
