Pentax PF-80 ED 80mm
Pentax created this new, waterproof, straight-through 80mm scope to take
advantage of the time-honored 1-1/4" Pentax telescope eyepieces. You can
get six interchangeable fixed eyepieces, originally designed for astronomy
and low-light viewing conditions, and a 20-60x zoom. The scope body is
waterproof even without the eyepiece attached. Remarkably, the Pentax
zoom eyepiece itself is also waterproof.
The Pentax zoom has extra long eye relief (20mm). The ring that changes
the zoom's magnification is broad and unusually easy to turn. As with
the Leica scope, you twist the front of the eyepiece to dial up the precise
amount of eye relief that fits you and your eyeglasses.
Pleasant rubber housing covers the magnesium-alloy frame of the straight-through
scope. There's an extendable sunshade and a sight on top to help you aim.
The focus wheel, at top right of the prism housing, turns smoothly.
