Eschenbach Optics 10x42 Farlux APO Binoculars

The farlux APO 10×42 by Eschenbach is a high-quality roof prism binocular designed specifically for demanding nature and bird watchers. Here are the key features at a glance:
Features & Equipment Extra large field of view: With a super wide-angle design, the binoculars offer a field of view of 122.5 m at 1,000 m, creating a very open experience, especially for nature observation. Apochromatic optical system (APO): The binoculars use fluoride-containing ED glasses (Extra-Low-Dispersion), resulting in very natural and brilliant color representation. Color fringing at the edge of the image is significantly minimized. High light transmission: Over 90% light transmission thanks to fully multi-coated lenses. Field-flattening optics: The image field is "flattened," which improves sharpness, especially at the edges. BaK-4 prisms: With phase-corrected coating (dielectric), leading to very high image brilliance. Robust housing: The housing is made of impact-resistant magnalium – very stable and durable. Water & dirt repellent: Objective and eyepiece surfaces are coated, making it difficult for water and dirt to adhere. Waterproof & nitrogen-filled: The binoculars are waterproof and filled with nitrogen to prevent internal fogging. Glasses wearers' eyepieces: Glasses wearers (e.g., with sunglasses) have an optimal field of view. Tripod thread: There is a stable thread for a tripod – practical for longer, steady observations. Warranty: 10 years manufacturer's warranty + "GarantiePlus" from Eschenbach.

Usage & Application Area

These binoculars are ideal for: Bird watching: Large image area, sharp optics & high light transmission assist in nature observations. Nature enthusiasts: For anyone who spends a lot of time outdoors and values image quality. Dusk observations: Thanks to the 42 mm objective, good visibility is still possible in low light conditions. Longer observations: The stable housing, field-flattening optics, and tripod thread make the binoculars comfortable for longer sessions.
