The 15x56 Conquest HD Binocular from ZEISS is designed to provide optimal performance in all light and weather conditions. Its performance comes from a combination of extra-low dispersion (ED) glass and fully multi-coated lenses and prisms. The ED glass corrects for chromatic aberration across the entire field of view, ensuring true color transmission with little to no distortion. Taking full advantage of the large 56mm objectives, the lenses have ZEISS' T* anti-reflective coatings, which minimize light loss and maximize the amount of light getting through the optics. The prisms are phase corrected to increase contrast. These optical coatings and glass produce a binocular that performs well, especially in low-light conditions, with bright high-contrast images and true color transmission across the entire 69° apparent angle of view.
Designed for rigorous use in the field, it is nitrogen filled and O-ring sealed for water and fogproof performance year-round in all weather conditions. The large center focus wheel is accessible with either hand and easy to use, even with gloves. Rubber armoring on the outside of the body provides a safe and secure non-slip grip in wet or cold conditions and offers protection against drops and impacts. The click-stop twist-up eyecups let you customize your eye relief whether you wear glasses or not. If you're going to be glassing for prolonged periods, the Conquest HD is tripod mountable with the included adapter.
Performance
- 15x magnification
- Large 56mm objective lenses boost light-gathering ability for improved views in low light, produce a wide exit pupil to limit vignetting, and present a generous field of view
- Compact Abbe-Koenig roof prism design produces a less folded light path than conventional roof prisms to decrease spherical and chromatic aberration
- Fully multi-coated with ZEISS' T* anti-reflective coatings for more than 90% light transmission
- Extra-low dispersion (ED) glass elements eliminate chromatic aberration across the entire field of view with little to no distortion
- Phase-corrected prisms produce high-contrast images with true color saturation
- LotuTec moisture/abrasion-resistant coating causes moisture, including snow and rain, to bead up and roll off the lens surface
- Wide 69° apparent angle of view limits the appearance of distracting hand shake that is common when holding high-power optics such as this
- 240-foot field of view at 1000 yards
Use and Handling
- Closed-bridge configuration provides a solid and steady platform for the internal focusing mechanism
- Large slip-resistant center focus wheel is easy to manipulate, even in cold and wet weather or while wearing gloves
- ±4 right-eye dioptric adjustment enables tack-sharp focus even for those who wear corrective eyewear
- 57-74mm interpupillary adjustment range
- Tripod mountable with included adapter
- Click-stop twist-up eyecups for customized eye relief with or without eyewear
- Long 18mm eye relief improves viewing comfort and reduces eyestrain, especially during long glassing sessions
- 3.7 mm exit pupil
