Rodenstock / ALPA HR Alpagon 4.0/50 mm, SB34, in Aperture Unit - custom made for ALPA by Rodenstock.
HR ALPAGON 50 mm - for perfect details
Anyone who automatically thinks of a standard focal length at term 50mm exposes himself as a 35mm photographer - at least regarding ALPA dimensions. In medium format, the HR ALPAGON 50mm plays the role of a moderate wide-angle lens, which is often referred to as a "report wide angle". This aspect makes it the ideal complement to the super wide angle HR ALPAGON 32mm and the "normal lens" HR ALPAGON 90mm with which it forms the "Holy Trinity" at ALPA. Like its "siblings" (HR ALPAGON 32mm and 90mm), the HR ALPAGON 50mm is optimized for the perfect resolution of even the finest details, guaranteeing extremely detailed and vivid images with perfect micro-contrast and tonal values. As with the other lenses in this range, the "50s" also recommend the use of a perfectly matched lens hood.
Warning: If a short barrel lens is attached to an ALPA body without an appropriate adapter, mechanical damage to the rear lens element and the camera is possible. The focal plane shutter of the ALPA 12 FPS can also be damaged.
