Product Overview

The Pentax SMC XW 7mm Eyepiece is built for shooters and spotters who care about what they see, not how shiny the spec sheet looks. With a 70° apparent field of view and a generous 20mm of eye relief, it gives you a wide, comfortable picture that makes picking out detail at distance feel easy – whether you’re glassing a hillside for goats or checking tight groups on a target. The high‑refraction, low‑dispersion lanthanum glass and full multi‑coatings keep the image bright and sharp, with minimal colour fringing, so you can trust what you’re seeing through the scope.

Designed around a 1.25" barrel, the XW 7mm drops straight into Pentax PF‑series spotting scopes and any telescope that takes standard 1.25" eyepieces. JIS Class 4 weatherproofing means it’s happy working in drizzle, dew and typical Aussie coastal moisture, without you babying it. The helicoid rubber eyecup lets you fine‑tune eye position, and the removable eyecup exposes a 43mm thread for mounting compatible camera or adapter gear. If you want a rugged, no‑nonsense eyepiece that delivers serious magnification and field performance for both terrestrial and astro use, this Pentax XW 7mm is a very solid bit of kit.
