With the Conquest 12×45, Zeiss apparently wanted to come out with a 12x binocular that was significantly smaller and lighter than the common 12×50 models already on the market. In fact, the Conquest is lighter than any other regular 12x (not counting the new small image stabilized binoculars from Canon, Fujinon, and Vixen). But otherwise, the result was less than convincing. Relatively narrow field of view, a slightly dull image, limited sharpness and mediocre contrast made the 12×45 T not a big success, esp. when it’s price was around CHF 1’000. Zeiss must have been happier with its other (non-HD) Conquest models. Production was stopped around 2012.
