High-Performance Model with Superior Optics
A 77mm objective lens in a compact body. With the portability and compactness of a 60mm class scope and the optical performance of an 80mm class scope, this model will satisfy both experienced users and beginners.
77MM XD LENS: The PROMINAR models have an XD objective lens with low dispersion properties to diminish chromatic aberration. Like the Prominar models, the concave lens paired with the XD lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree.
COMPACT SIZE: The adoption of the inner focus system keeps the prism box light and compact, realizing a large 77mm objective lens in a body length of a 60mm class scope.
MAGNESIUM ALLOY BODY: The magnesium alloy body decreases the weight of the scope while providing a rugged structure that can withstand the severest conditions.
DUAL FOCUS MECHANISM (QUICK & FINE FOCUSING): The dual focus mechanism allows focusing in two revolutions and fine pinpoint accuracy in one system.
EYEPIECE LOCKING MECHANISM: The eyepiece locking mechanism secures the eyepiece to the scope body and prevents it from getting lost or falling off suddenly.
TRIPOD MOUNT: The addition of a brass insert to the tripod mount of the scope allows the scope to be secured to both 1/4 and 3/8 inch mount tripods.
WATERPROOF & FILLED WITH DRY NITROGEN GAS: The housing is waterproof to JIS* Protection Class 7** and filled with dry nitrogen gas to prevent the lens from fogging.
*JIS=Japanese Industrial Standard
**The Scope is not intended for use underwater
