Fluoride-containing, premium-glass lenses efficiently transmit all wavelengths of visible light for bright images that are color faithful, crisp, and rich with detail. Coatings on all lenses minimize glare while maximizing contrast, phase-corrected prisms ensure that images are rendered with clarity, and field-flattener lens technology eliminates geometric optical distortion throughout the zoom range. And because life in the field can be messy, the SWAROCLEAN lens coating makes it easier to clean away dirt such as water marks, insect repellents, or tree resin.
The included 20-60x eyepiece features a wide viewing angle and generous eye relief. The eyepiece quickly attaches to and detaches from the objective assembly's bayonet mount for easy disassembly, transportation, and storage. The nitrogen-purged, O-ring sealed, and rubber-armored housing ensure water, fog, and shockproof performance in almost any environment. A removable sighting aid helps in target acquisition when a camera is mounted to the eyepiece.
