Product Overview

Built for serious glassing, the Pentax XF SMC 6.5–19.5mm Zoom Eyepiece turns your PF‑65 series spotter into a flexible, hard‑working field tool. With a 20–60x zoom range on a 65mm Pentax scope, it lets you roll from wide, context‑rich views to tight detail on distant birds, game or targets without swapping eyepieces. The apparent field of view runs from 42° to 60°, so you’re not staring down a tunnel at higher power, and the 11–15mm eye relief keeps things comfortable whether you’re bare‑eyed or wearing sunnies.

Optically, it’s classic Pentax: extra‑low dispersion lanthanum glass, full smc multi‑layer coatings and a 6‑element/4‑group design for bright, high‑contrast images with minimal aberrations. The American‑standard 31.7mm (1.25") sleeve means it’ll drop into most 1.25" focusers, and the waterproof, fog‑resistant build handles wet gullies, coastal spray and outback dust without fuss. A twist‑up, click‑stop rubber eyecup and user‑friendly rubber eyepiece ring round it out, giving you a secure, comfortable view all day on the hill or at the range.
