Spindler & Hoyer, another great German brand in fine optics and precision engineering with more than 120 years of history. This little and lightweight instrument proved that very well. It's my smallest 8X30 binoculars, even smaller than KERN Pizar 6X24 and weighs only 360 g. Despite the size it surprises with very good optical performance. It's sharp, bright with good contrast and has very neutral colours. Only field of view is a little bit narrower than in best porro "full size" 8X30 binoculars. Still wide enough, especially for today's standards. Definitely does not deserve to be overlooked among the collectors. It was a budget German binocular. And even today you can get one really cheap.
Note: It has some kind of fabric strips on the sliding ocular tubes which fall apart within the years and are hard to replace.
