Alpen Optics Apex XP 10x42 ED

• ED glass optics: Extra-low-dispersion glass helps reduce color fringing and improves contrast, so fine detail stays easier to separate when scanning birds, game, or distant terrain.
• 10x42 all-round configuration: The 10x magnification gives useful reach for open-country observation, while the 42 mm objectives keep the binocular manageable for long walks and day-long field use.
• PXA and HR prism coatings: Phase-corrected and metallic-coated prisms support better resolution, color fidelity, and brightness, which is especially helpful in mixed light and at dawn or dusk.
• Waterproof, nitrogen-filled housing: The sealed construction and nitrogen purging help the binocular stay reliable in rain, cold mornings, and rapid temperature changes that can cause internal fogging.
• Central focus with right-eye diopter: Fast central focusing and separate diopter adjustment make it easier to fine-tune the view to individual eyesight and keep observation quick and efficient in the field.

About the Alpen Optics Apex XP Series

Alpen Optics Apex XP binoculars sit above the standard Apex models in the company’s lineup and are built for users who want a more refined optical package for hunting, birding, long-range observation, and general outdoor viewing. The series combines ED glass with BaK-4 roof prisms, giving it a clear emphasis on improved contrast, better control of chromatic aberration, and dependable image brightness in a compact binocular format.

A defining part of the series is its use of PXA phase coating and HR metallic prism coatings. In practical terms, these treatments help preserve resolution, color fidelity, and light transmission, so the image remains cleaner and more natural when viewing detail at distance or in difficult light. The current lineup includes 8x42 ED, 8x56 ED, and 10x42 ED models, as well as a 10x42 ED version with an integrated laser rangefinder, which shows that the series is aimed at field users who need more than basic observation. Across the range, the waterproof, nitrogen-purged construction reflects a design focused on reliable outdoor use rather than casual occasional viewing.

About the Alpen Optics Apex XP 10x42 ED

The Alpen Optics Apex XP 10x42 ED is the most versatile format in the Apex XP family for users who need a balance of reach, brightness, and portability. 10x magnification gives noticeably more detail on distant subjects than an 8x binocular, which makes this model well suited to open-country hunting, raptor watching, shoreline observation, and general wildlife use where subjects are often beyond close woodland distances. At the same time, the 42 mm objective lenses keep the binocular compact enough for regular carry, while the 4.2 mm exit pupil supports a bright, easy view in normal daylight and useful performance toward the edges of legal shooting light.

The optical system is built around ED glass, fully multi-coated lenses, and a roof prism design, all working together to improve sharpness, contrast, and color neutrality. That matters in practice when trying to distinguish feather detail, antler points, or subtle movement against busy backgrounds. The 113 m field of view at 1000 m is wide enough to keep scanning efficient, while the 2.5 m close focus also makes the binocular practical for nearby observation. A central focusing system keeps adjustments quick, and the right-eyepiece diopter with a - 5.0 / + 5.0 dpt range helps tailor the image to the user’s eyesight. The waterproof, fogproof, nitrogen-filled housing and 703.00 g weight make it a serious field binocular that remains manageable for extended use.

About Alpen Optics

Alpen Optics was founded by Tim Gardner in December 1996, and the company introduced its first products in 1997. Its history identifies Rancho Cucamonga, California, as headquarters. The brand focuses on field optics including binoculars, spotting scopes, riflescopes, and thermal optics, with binocular lines such as Apex XP, Teton, and Rainier covering different performance levels and uses.

Within binoculars, Alpen Optics is known for combining practical outdoor design with optical features such as BaK-4 prisms, PXA phase coating, and HR metallic coatings. In 2018, Explore Scientific acquired Alpen Optics’ trademarks and designs, linking the brand to a broader optics portfolio while preserving its emphasis on observation and hunting-oriented products. That background helps explain why models like the Apex XP series focus on weather resistance, usable field ergonomics, and optical systems designed for real outdoor conditions rather than display-case specifications alone.
