|Kowa XD Lenses||Kowa’s HD Lenses (eXtra-low Dispersion glass with similar characteristics to fluorite crystal) combines with a special dispersion concave lens to reduce a very high percentage of chromatic aberration for the ultimate viewing experience.|
|Waterproof and Fogproof||The housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging to ensure image clarity.|
|Dual Focus Mechanism||Kowa’s well-deleveoped focus system has progressed to a dual focus system with smooth movement at high magnifications for pinpoint accuracy in image display. The quick focus can easily shift from infinity to 5m in two revolutions with the large and maneuverable knob. The fine focus moves fluidly to create pinpoint accuracy and is extremely useful at high magnifications and with digiscoping systems.|
|Thixomolded Magnesium Alloy Body||The magnesium alloy body is constructed by a sophisticated process called thixotropic molding to give the strength and feel from a traditional body, but with much lighter weight. The rugged structure can tolerate the severest conditions and to deliver the highest level of confidence and security.|
|Kowa’s Eyepiece Locking Mechanism||Kowa’s standard eyepiece bayonet mount includes a locking mechanism to prevent the eyepiece from getting lost or falling out unexpectedly.|
