1 1.25incH / 31.7MM eYepiece connector
The large-sized, 31.7mm (1.25inch) eyepiece connector will give
you a serious advantage. This sizeable connector allows you to use
high-end eyepieces (from PENTAX or specialist manufacturers) that
provide a clearer, brighter and edge-to-edge sharper image. The
large receptacle also provides you with a fundamentally more
stable basis to use your spotting scope for photography.

As with binoculars, spotting scopes are also equipped with a prism
system. The function is two-fold: turning the image the correct way
up but also to reduce the overall length of the scope. At PENTAX we
favour a porro prism system (with the eyepiece optical line off-set
from objective lens). Porro prism scopes offer a better balanced
depth perception and a wider field-of-view. The PENTAX
porro prism is made of high index BaK4 prism glass which
is standard in all our scopes.

2 sMc Multi-laYer lens coating
The PENTAX SMC lens coating is renowned in the Industry. Not only
does this coating improve contrast and resolution – it also optimises
light-transmission throughout the whole light spectrum, so
allowing well-balanced and colour-correct image reproduction.
3 Functional HigH-tecH-Design
PENTAX spotting scopes are built from solid yet lightweight Magnesium-alloy
with full body rubber armouring. A built-in retractable
lens shade cuts excessive light and protects against the weather
elements (standard on all scopes!). No need to worry about
rain anyway – all the PF-bodies are fully waterproof and
Nitrogen purged (JIS Class 6).

The ultimate objective when building top optics is to reproduce the
image free from chromatic aberration and absolutely colour correct.
This is an absolute must for critical users but can only be achieved
by using ED-glass (Extra-low Dispersion) in combination with Lanthanum
glass. This sophisticated rare-earth mineral has very low
dispersion and favourable refraction values. You will find
ED-objective lens elements, in combination with Lanthanum
lens elements, on all PENTAX spotting scopes.
