The 8x40 Zeiss Conquest binocular is the smaller of the two full-sized versions of the Conquest line. Weighing just under 29 oz. and measuring 6 inches tall by 5 inches wide, the 8x40 T* Zeiss Conquest delivers full-sized optical performance at a medium-sized price. Featuring Zeiss’ proprietary T* multi-coating on the Abbe Koenig-type prisms with full phase correction, the 8x40 Conquest delivers the kind of crisp, bright images that fans of Zeiss optics have admired for years. Nitrogen-purged to be internally fog proof and completely waterproof as well, Zeiss 8x40 Conquest binoculars are rugged and durable in addition to providing excellent optical performance.
