The jump from 42mm to 50mm objectives makes a real difference at dawn and dusk — more light in, brighter image out. The Alpen Chisos 10x50 pairs that extra light-gathering with ED glass and PXA phase-coated prisms for the color accuracy and edge sharpness that 10x magnification demands, all in a magnesium chassis built for serious field use.
Key Features
- 50mm Objective Lenses — Gathers noticeably more light than 42mm models, keeping views bright and detailed in the low-light conditions where wildlife activity peaks.
- ED Glass — Extra-low dispersion elements eliminate chromatic aberration at 10x, keeping plumage colors true and fine detail sharp against bright sky and backlit canopy.
- PXA Phase-Coated BaK-4 Roof Prisms — Phase correction preserves resolution and contrast edge-to-edge for confident ID work at distance.
- Fully Multi-Coated Optics — Every air-to-glass surface treated for maximum light transmission and minimal glare.
- 6.5-Foot Close Focus — Tight enough for feeder birds, butterflies, and wildflowers — versatile across near and far subjects.
- Lightweight Magnesium Housing — Durable yet comfortable for all-day carry with textured grip panels.
- Waterproof & Nitrogen-Filled — Sealed against rain and humidity, internally fog-proof through rapid temperature swings.
- 16mm Eye Relief with Twist-Up Eyecups — Comfortable viewing for glasses wearers across extended sessions.
Ideal For
- Birders who want 10x reach with extra brightness — 50mm objectives outperform 42mm in dawn, dusk, and canopy shade where plumage ID depends on available light.
- Hunters who glass ridgelines and treelines in marginal light and want ED color accuracy to distinguish game from terrain.
- Wildlife observers who work from blinds or fixed positions and value brightness over ultralight portability.
- Astronomy enthusiasts looking for a step up from 42mm for brighter views of the Milky Way, open clusters, and bright nebulae.
- Glasses wearers who need comfortable eye relief without sacrificing field of view.
