Product Overview

Built for serious glassing, the Pentax SMC XW 14mm Eyepiece slots straight into your Pentax spotting scope or telescope and gets to work. With a 70° apparent field of view and generous 20mm eye relief, it gives you a wide, comfortable picture window on the world – from tight feather detail on a distant raptor to crisp lunar craters after dark. High‑refraction, extra‑low dispersion lanthanum glass and full multi‑coatings keep the image bright, sharp and true‑to‑colour right across the field, so you can pick fine detail and subtle contrast without fighting glare or fringing.

Weatherproof to JIS Class 4 and built around a rugged 1.25" barrel, the XW 14mm is ready for real Aussie conditions – drizzle on the coast, dewy nights inland, and long days in the field. The helicoid eyepiece ring and adjustable eyecup make it easy to find a comfortable viewing position, whether you wear glasses or not. Drop it into a PF‑series spotter or your favourite astro rig and you’ve got a dependable mid‑power workhorse that excels at both birding and astronomy, day in, day out.
