VIVI Falcon 10x50ED Bright Low-Light ED Binoculars
VIVI Falcon 10x50ED binoculars pair 10x magnification with a large 50mm objective to create the brightest, most balanced model on the Falcon 42/50 platform. The 5.1mm exit pupil and 25 relative brightness feed more light to your eye than any 42mm model can, while the 22.4 twilight factor and 3.6" resolution keep that light organized into sharp, high-contrast detail well past the hours when smaller binoculars fade.
Product Description
The VIVI Falcon 10x50ED binoculars pair 10x magnification with a large 50mm objective to create the brightest, most balanced model on the Falcon 42/50 platform. The 5.1mm exit pupil and 25 relative brightness feed more light to your eye than any 42mm model can, while the 22.4 twilight factor and 3.6″ resolution keep that light organized into sharp, high-contrast detail well past the hours when smaller binoculars fade.
The ED extra-low dispersion objective and BAK4 roof prism with FMC multi-layer coating deliver 82% light transmission with faithful, natural color. Whether you are glassing a hillside at last light, watching shipping from a seawall or checking equipment on an overcast morning, the 10x50ED keeps the image bright and usable.
ED Glass for Clearer, More Vivid Images
The ED extra-low dispersion lens reduces the chromatic aberration caused by different wavelengths of visible light, helping support sharper images, stronger contrast and more natural color reproduction — advantages that grow more visible in the low-contrast light of dawn and dusk.
BAK4 Prism with FMC Multi-Layer Coating
The BAK4 prism improves light transmission and viewing clarity, while the FMC multi-layer coating provides anti-reflection performance across the visible range, helping produce realistic, natural observation colors.
50mm Low-Light Balance
The 10x magnification and 50mm objective balance reach with light collection: a 5.1mm exit pupil matches the eye’s adapted pupil in dim conditions, so the image stays bright when the light drops.
IPX7 Nitrogen-Filled Waterproof Protection
The binoculars feature IPX7 waterproof protection and nitrogen filling, with construction specified to withstand a 30-minute, 1-meter water-intrusion test — reassuring performance for coastal, marine and all-weather field use.
Durable, Comfortable Handling
The PC/ABS composite body with PVC surface cover and anti-slip detailing provides a secure grip, and the 17.5mm eye relief with twist-up eyecups keeps the full field of view comfortable with or without glasses.
Why Choose the VIVI Falcon 10x50ED?
The VIVI Falcon 10x50ED is the balanced choice of the Falcon 50mm pair: it keeps the useful 10x reach of the 42mm models but steps up to a 5.1mm exit pupil, 25 relative brightness and a 22.4 twilight factor, producing a visibly brighter image in overcast, forest and coastal light. With a 3.6″ resolution figure, it also delivers the sharpest image of the 42/50 platform.
Compared with the VIVI Falcon 12x50ED binoculars, the 10x50ED offers a wider 107m/1000m field of view versus 86m, a brighter 5.1mm exit pupil versus 4.2mm, and far more comfortable 17.5mm eye relief versus 13.5mm — making it the easier, brighter glass for general observation, marine use and long handheld sessions. The 12x50ED is the specialist alternative when raw distance detail outweighs field width and comfort.
Within the Falcon family, the 42/50 platform uses a durable PC/ABS composite body with 82% light transmission. For observers whose sessions regularly run into true dawn and dusk twilight, the Falcon 56 series upgrades to a magnesium-aluminum alloy body, phase-coated BAK4 prisms and 84% light transmission — a premium low-light platform at a higher weight class.
