Sports cars are lightweight, so is the Hensoldt Sportglas. Weighs only 432 g! This is a great achievement for center focus 8X30 binoculars made somewhere between 1936 and 1943. For example, the same size Deltrintem weighs 100 g more. It's not the brightest binoculars around, let's say average. But its colours are very neutral and center sharpness is pretty good. Brown leather looks quite unique.
