ALPA Apo Switar 5.6/36 mm

What a diva and what a great lens. Inverse curvature of field and only a handful were able to set the calibration correctly. For many architecture photographer this was and sometimes still is their "bread and butter" lens. Stellar with digital back and sensors of 9 down to 6.8 micron pixel size, demanding to control below this lens was one of the cornerstones of the ALPA lens arsenal.
