Dawn and dusk are when the action peaks — and when most compact binoculars lose the plot. The Alpen Apex 10x50 bridges the gap between standard 42mm portability and dedicated low-light 56mm models, with 50mm objectives and a 5mm exit pupil that keep views bright and usable into twilight, backed by PXA phase-coated BaK-4 prisms and HR metallic coatings for the contrast to match.

Key Features

• 50mm Objective Lenses — Larger than standard 42mm for noticeably brighter images in low light, without the bulk and weight jump of 56mm models. A practical middle ground for observers who split time between carry and stationary use.
• PXA Phase-Coated BaK-4 Roof Prisms — Phase correction preserves resolution and contrast across the full field, with HR metallic coatings boosting prism reflectivity for maximum brightness per photon.
• Fully Multi-Coated Optics — Every air-to-glass surface treated to reduce glare and maximize light transmission — effective when glassing across water, snow, or bright sky.
• IPX7 Waterproof & Nitrogen-Filled — Submersible to 1 meter for 30 minutes and internally fog-proof through rapid temperature swings between vehicles and cold field conditions.
• 10x Magnification — Pulls distant subjects closer than 8x for tighter detail on birds, game, and terrain features at range.
• Twist-Up Eyecups with Generous Eye Relief — Multiple lock positions for comfortable full-field viewing with or without glasses during extended sessions.
• Rubber-Armored Body at 2.6 lbs — Absorbs field impacts and provides secure grip, balanced enough for steady handheld use at 10x.

Ideal For

• Hunters who glass at dawn and dusk and want more light-gathering than 42mm without committing to the size of 56mm — 50mm hits the sweet spot for mixed use.
• Birders who want 10x reach for distant ID work with enough brightness for early morning and late afternoon observation sessions.
• Wildlife observers who work from mixed positions — blinds, vehicles, and on foot — and need a binocular that performs across all of them.
• Astronomy enthusiasts looking for a step up from 42mm for brighter views of the Milky Way, open clusters, and bright nebulae.
• Budget-conscious upgraders who want serious optical performance with phase-coated prisms and multi-coated glass — without stepping into the ED glass price tier.
