Ferolix JR06-0842 is a premium compact 8×42 roof prism binocular engineered for Outdoor Observation, bird watching, wildlife viewing and nature sightseeing. Built with BaK4 roof prisms and FMC full multi-coated optics, this model delivers outstanding light transmission up to 80%, bringing bright, high-contrast images even in twilight and low-light environments.
All lenses and prisms are made of high-grade optical glass. FMC (Full Multi-Coating) means all optical surfaces are anti-reflection coated, effectively cutting down glare and light loss. The 7° wide angle of view offers 122m viewing range at 1000 meters, making it easy to track fast-moving birds and wildlife. The 1.5m ultra-short close focus allows sharp viewing of nearby objects, perfect for observing flowers, insects and small creatures.
17mm eye relief with twist-up eyecups provides flexible viewing for both eyeglass wearers and non-glass users. Diopter adjustment range from -4 to +4 diopters compensates for eyesight difference between two eyes. Interpupillary distance adjustable from 56mm to 76mm fits a wide range of face shapes. Central focus system supports quick and precise focusing.
The binocular housing uses durable semi-aromatic thermoplastic PPS material with PVC cover. IP7 waterproof rating supports short-term immersion, protecting the optics against rain, splashes and humid outdoor conditions. Single unit weight is only 710g for comfortable all-day carrying. Color: Black.

FMC stands for Full Multi-Coating. It means every optical surface of the lens and prism has anti-reflection multi-coating. Compared with MC coating, FMC achieves higher light transmittance, less reflection and better image contrast, ideal for low-light outdoor scenarios.
BaK4 is high-quality barium crown optical glass. Roof prism design creates a slim, compact binocular shape. BaK4 prisms reduce vignetting and deliver brighter edge-to-edge image quality, widely used in mid-high end outdoor binoculars.
IP7 rating indicates the binocular can withstand temporary submersion in water up to 1 meter depth for a short time. It guards against rain, water splashes and moisture, suitable for rainy and humid outdoor environments.
Close focus is the minimum distance you can focus clearly. This JR06-0842 reaches 1.5m ultra-close focus, allowing you to observe nearby plants, butterflies and small wildlife clearly.
