Since they came into the market, the various models of the Conquest HD line of binoculars have gained reference status for their particular size. This is especially true for the 8×42 model. Less expensive than many competing “subprime” instruments from other manufacturers, well designed and finished, with excellent central and good off-axis sharpness, and overall very acceptable CA correction and stray-light control, the Conquest HD shows in many ways characteristics of a “premium” binocular. One complaint has been voiced frequently: although the Conquest HD features quite a nice eye relief of 18mm, the eyecups cannot be extended far enough and so many users have had trouble with “kidney-beaning” (dark shadows at the edge of the image). This, however, is only an issue with the 8×42 model, not with the others of the Conquest HD line (and Zeiss is offering optional eyecups upon request), and there are methods to hold the binocular so that kidney-beaning does not become an issue.
