When Zeiss in 2012 introduced its new Conquest “HD” line of binoculars (and, by the way, the then brand new Victory HT), the previous “Conquest T*” series which consisted of 10 different models (8×30, 10×30, 8×40, 10×40, 12×45, 15×45, 8×50, 10×50, 8×56, 10×56) was phased out after a short period of “overlap” with the new HD models. In earlier times, binoculars in size 8×50 tended to have porro prisms (e.g., see separate posts “Carl Zeiss Jena Nobilem Super 8×50”, https://binocular.ch/carl-zeiss-jena-nobilem-super-8×50/  and “Carl Zeiss Jena Octarem 8×50”, https://binocular.ch/carl-zeiss-jena-octarem-8×50/), later on, roof prisms became the norm, as in this Zeiss Conquest T* 8×50, which features Abbe-König prisms (almost all other 8×50 glasses feature Schmidt-Pechan prisms, e.g. the “Leica Ultravid 8×50 HD+”, see separate post https://binocular.ch/leica-ultravid-8×50-hd-plus/). The Conquest T is very lightweight for its size, thanks to a body made of polycarbonate (instead of metal, like the Conquest HD), and provides an overall good optical and mechanical performance; in the 8×50, the field of view is slightly narrower than in other roof prism models (and much narrower than in the “old times” with Nobilems and Octarems).
