XF Series

Developed for exclusive use with the compact PF-65ED and PF-645EDA spotting scopes, the smc PENTAX XF series offers a choice of three distinctive eyepieces: two unifocal models with a long eye relief and a wide angle of view, and one zoom model with a 20-60X variable magnification range. When the rotatable eyecup is removed, they feature an adapter-mounting screw (30.5mm in diameter with a 0.5mm pitch for the unifocal models, and 43mm in diameter with a 0.75mm pitch for the zoom model).

The XF8.5 and XF12 are standard unifocal eyepieces, offering a focal length of 8.5mm and 12mm and a magnification of 46 and 32.5 times, respectively, with a 60-degree apparent field of view and a long 18mm eye relief. They also feature an extendible eyepiece ring with four click-stop positions.

The XF Zoom Eyepiece 6.5mm-19.5mm features a focal-length range of 6.5mm to 19.5mm for a magnification of 20 to 60 times, with an apparent field of view of 42 to 60 degrees and an eye relief of 11mm to 15mm. It also offers a user-friendly rubber eyepiece ring that never becomes too cold to touch while minimizing the risk of scratching the observer’s eyeglasses.

These eyepieces also come with a filter-mounting screw and an adapter-mounting screw.
