The Pentax 8x30 and 10x30 delivers bright clear images
without being over sized or cumbersome owing to its anti-reflection
fully multicoated 30mm objectives which maximize light transmission to
produce the brightest views possible.
Utilizing traditional porro prisms produce scenes with a
rich depth of view over similarly sized roof prisms with the added
benefit of a larger surface area to give it a comfortable feel in the
hand. BAK4 porro prisms are incorporated and anti-reflection fully
multicoated optics offers clear and sharp images. Knurled center
focusing wheel, twist-up eyecups for use with or without eye wear,
closed bridge configuration and tripod mountable with optional adapter
adds to its easy handling.
The housing is made of corrosion and impact-resistant
fiberglass reinforced polycarbonate polymer. The material is also
temperature-resistant allowing for its use in extreme climates while
reducing expansion and contraction wide temperature swings can cause
which can make the optical components move out of collimation over time.
Its optical tubes are nitrogen-filled and O-ring sealed so they can are
submersible to 3.3', as well as fogproof in all weather conditions.
