Glassing a treeline at dawn with 10x magnification and getting nothing but haze and color fringing means your optics aren't keeping up. The Alpen Apex XP 10x42 pairs ED fluoride glass with PXA phase-coated BaK-4 roof prisms and HR metallic coatings to deliver the contrast and color accuracy that separate a confident ID from a second guess — at a price point well under the premium tier.

Key Features

• ED Fluoride Glass — Extra-low dispersion elements eliminate chromatic aberration on high-contrast edges, keeping bird plumage, antler tines, and distant detail sharp and color-true.
• PXA Phase-Coated BaK-4 Roof Prisms — Phase correction maintains resolution and contrast across the full field, with HR metallic coatings boosting reflectivity for brighter views in marginal light.
• Fully Multi-Coated Optics — Every air-to-glass surface treated for maximum light transmission and minimal glare, even when glassing across water or snow.
• IPX7 Waterproof & Nitrogen-Filled — Submersible to 1 meter for 30 minutes and internally fog-proof through rapid temperature shifts between vehicle and field.
• Twist-Up Eyecups with 15.2mm Eye Relief — Multiple lock positions for comfortable full-field viewing with or without glasses during extended sessions.
• Lightweight at 2.3 lbs — Balanced for all-day carry on long hikes without neck fatigue, yet solid enough to feel field-ready.

Ideal For

• Birders who need sharp, color-accurate 10x views to distinguish plumage details at distance — especially during dawn and dusk activity peaks.
• Hunters who glass open terrain and treelines in variable light and want reliable contrast without paying four figures.
• Hikers and nature observers who value lightweight, weatherproof optics that perform from forest canopy to alpine ridgelines.
• Glasses wearers who need full field of view without removing eyewear.
• Upgraders from entry-level binoculars stepping into ED glass and phase-coated prisms for the first time — this is where the optical quality jump becomes obvious.
