Zeiss Victory FL Binoculars - Roof Prism

State-of-the-art glasses for uncompromised performance. FL glass (extremely low dispersion with fluoride ions) and AOS design (Advanced Optical System, featuring lead- and arsenic-free glass in multiple thin elements) give you as-close-to-perfect-as-it-gets color correction, clarity, and resolution. Widest usable fields-of-view available, with rapid, precise, intelligently tuned close focus to 7 feet. Zeiss T* multicoatings and P* prism coatings produce bright, high-contrast views. Adaptive eyecups twist up, with locking intermediate settings to fit your eyes. High-impact glass fiber-reinforced polyimide body is fully waterproof and nitrogen purged with magnesium and alloy reinforcements where needed. High-tech dual focus and diopter control. 32mm objective models feature high-efficiency Pechan prisms, with 72-layer dielectric mirror coatings for uncompromised brightness, but in a compact, lightweight design. 42mm objective models give you the brightest, sharpest views possible with high-efficiency Abbe-Konig prisms which require no mirror coatings.
