The Alpin used to be Kern’s top non-military 8×30 model, with 10m more field of view than the same size “Pizar”. It was a popular example of a whole range of high quality 8×30 Porro binoculars from various manufacturers , on the market in the period between about 1950 and the early 1970s. Good central sharpness, not-so-good edge sharpness, bright image, lightweight, compact, mechanically impeccable (zero “rocking” of the bridge!). A nice detail: the central focusing wheel is placed at the front end of the central hinge and operated with your ring finger, not your index.
