Before ALPA Capaul & Weber could take over the historic brand name SWITAR, HELVETAR served as a substitute brand. This name was used exclusively for lenses from Schneider Kreuznach (SK). In contrast to SK's sister lenses, Helvetar lenses always had a unified filter diameter of 67 mm.
The series began with the legendary Helvetar 48 and included the Helvetar 43, 48, 75, and 120 mm. Each of these lenses - like all ALPA lenses - was individually tested by hand and technically and photographically.
