Alpa 50mm F/1.8 Kern Macro-Switar AR Auto Lens {48} Description


The Kern Macro Switar 50mm f/1.8 AR lens was made in Switzerland by Kern Aarau exclusively for the Alpa 35mm cameras. Introduced in 1951, the Kern Macro Switar lens reached legendary status for its precision optics and hand-crafted elegance. The Switar 50mm Aprochomat gives the image of unique brilliance, with razor-sharp definition and high contrast at all apertures. The all-in-one macro lens seamlessly breaks through the near-distance barrier by focusing down to 7 inches. The lens also features Kern Visifocus depth-of-field scale. Macro Switar's exclusive provision for "point-blank" pictures allows the ALPA photographer to take close-ups without accessories.
