ALPA Capaul & Weber Ltd. also cares about the owners of historic Alpa 35mm lenses and offers now the possibility to use these vintage lenses on a current ALPA camera by introducing the ALPA Lens Module for Alpa 35mm lenses. Many of these lenses have their own unique image character and are waiting to be rediscovered.
We have tested the performance of an 8-element Macro-Switar 1.9/50 mm in close range. The historical lens can be focussed via a helical mount with an extra long travel to the scale of 1:2. The lens was produced from 1970 to the 1980s in just over 6000 copies. This corresponds to around a quarter of all 50mm lenses manufactured by Kern Aarau under this name for Alpa.
Here is the aperture series (crop) taken with a Phase One IQ3 100MP digital back (image circle used in this crop is approximatively 57 mm).
