Product Description
The VIVI Focus 10×56 binoculars combine 10x magnification with a 56mm large aperture, creating an evenly matched optical platform for observers who want both reach and brightness. A 5.59mm exit pupil, 31.4 relative brightness and 84% light transmission keep the image sharp and luminous from midday glare to the last minutes of dusk.
HD Optics with Reach
BAK4 phase-coated roof prisms and FMC multi-layer coating support the specified HD imaging performance, so distant subjects stay crisp and color-true even as the light softens.
Precise, Practical Control
The large center focus wheel is sized for gloved hands, and internal focusing keeps the optical assembly sealed and stable through the seasons.
Balanced Field Companion
A magnesium-aluminum alloy body sealed to IPX7 (1m immersion for 30 minutes) and an ergonomic anti-slip grip make the VIVI Focus 10×56 a dependable partner for travel, nature observation and project inspections.
Why Choose the VIVI Focus 10×56?
The 10×56 configuration is the all-rounder of the large-aperture VIVI Focus family. It splits the difference between brightness and reach: more magnification than the VIVI Focus 8×56 binoculars for pulling distant subjects closer, yet with a 5.59mm exit pupil that is still larger than fully dilated pupils in many adults — comfortable deep into twilight.
Compared with the VIVI Focus 12×56 binoculars, the 10×56 keeps a wider 6° field and an easier-to-steady image, while the 12×56 chases maximum long-range detail with its higher 25.9 twilight factor. If your observation mixes habitat scanning with subject study, the 10×56 is the balanced choice.
With 84% light transmission, a 23.66 twilight factor and an IPX7-sealed magnesium-alloy body, the VIVI Focus 10×56 handles nature observation, dusk wildlife watching and professional field inspection with equal confidence.
