This early 1970s Dialyt used to be one of the very good roof prism binoculars in this size available at that time, with a nice field of view of 7.7 degrees, which was considerably more than what the same size Zeiss 8×30 Porro (see separate post) from the 1960s provided (6.3 degrees). The missing phase coating becomes painfully obvious in the lack of sharpness and contrast when compared with current good 8×30 roof binoculars, but also the 8×30 Porro model from Zeiss clearly outperformed the Dialyt in this respect. On the other hand, the light weight, compact size and nice sweet spot make this bino still a pleasure to use.
