The 10x25 Conquest Binocular has all of the typical Zeiss accreditations, this binocular is indeed no exception. It is extremely lightweight, compact and can easily be taken anywhere due to its roof-prism design. The 10x25 conquest binocular is a great daylight performer. It produces brighter images than its Diafun predecessor. Thanks to the Zeiss advanced Phase corrected, "mirror-free," Abbe-Koenig prisms, all the Conquest binoculars are expected to produce edge-to-edge sharpness and unsurpassed resolution. Images appear stunningly contrasty in most lighting situations due to the Zeiss well renowned T* coatings.
