had this glass for a while, have seen very few around; maybe 4-5 mentioned in classifieds/ebay/forums - though i presume if i spoke/read German i’d see more reports. made in Germany Jena-zeiss east factory, before docter took over / re-branded, and across the line from west german zeiss 15x60 bga
terrific sized bino for a 15power glass, mass around 1.25-1.3kg [2.8lbs] based off a couple of measures, can be handheld for quite some period before fatigue sets in. much better than the fuji 16x70 or 15x70 nearly half their mass. length is 23cm x 18 across prism end, case is a very nice leather affair at about 12 inches, eye lens of the bino measures 18mm, which is intermediate for most binos i have
the mass compares favourably to both the zeiss & docter equivalents, which i read weigh in around 1.5-1.6kg, and the glass has the classic leather look textured finish of binos of old. the docter has a thicker smoother rubberised covering, the zeiss a military style graduated armour.
see pics below for size comparison with brunson 15x51 & kronos 26x70.
curiously there are no fov stated values on the bino, from what i have read in the limited info i have seen on them they were quoted at 4.6 degree fov. markings just show ausJena on the left and 15x60 Nobilem B on the right hand side. i believe the aus just stands for from, so from Jena -nice & practical
aperture appears to measure out correctly at 60mm, and exit pupil is pretty close to 4mm, so appear to be spot on 15x60. stated eye relief is 15mm, i measure actual a bit shorter than this, getting close to 11-11.5mm, recess of the eye lens is minimal, maybe only 1mm or so so i put actual ear around 12-13mm on my sample.
