pentaX eYepieces
coMpact precision engineering.
We at PENTAX believe that the eyepiece is crucial to the overall optical performance of spotting scopes. That is why our eyepieces
are engineered to the exacting standards originally required by the astronomy community. Furthermore, that is why we
made the 1.25inch (31.7mm) connector our standard. We are among an elite few who use rare materials like Lanthanum glass
to optimise light transmission for unsurpassed clarity and brightness. Successfully, it seems, since astronomers and ornithologists
agree that PENTAX eyepieces are among the best available world-wide.
Xw-series XF-series
The absolute high-end in eyepieces: from beginning to end fully
equipped to provide an edge-to-edge razor sharp image, free of aberration
and with maximum resolution and clarity.
• up to 8 lens elements in 4 groups. Fully blacked inside to
minimize internal reflections
• eD-glass elements that include lanthanum glass, to minimize
chromatic aberration and maximize well-balanced transmission
• extra lens elements to reduce spherical aberration of the human
eye (the so called “black-out” effect)
• Maximum usability and viewing comfort with 70° apparent
angle of view*
• eye relief at a comfortable 20mm, also eyewear users can have
a comfortable view
• jis 4 weatherproof so well protected against wet (outdoor)
conditions or night-time dew
• twist-up rubber eyecup
* except Zoom
We can economise but we will never compromise our optical quality.
The XF-series, in conjunction with the PF-65EDII / 65EDAII, offers
excellent value for money.
• 6 lens elements in 4 groups. Full blacked inside to minimize
internal reflections
• eD-glass elements that include lanthanum glass, to minimize
chromatic aberration and maximize a well-balanced transmission
• optimal usability and viewing comfort wit a 60° apparent
angle of view*
• eye relief up to a comfortable 18mm
• comfortable soft rubber eyecup
* except Zoom
