VIVI Spark 8×40 Wide Angle Binoculars
The VIVI Spark 8x40 binoculars are the wide-angle entry model of the VIVI Spark series, built on a classic Porro prism platform that combines 8x magnification with 40mm objective lenses. The result is the widest field of view in the Spark series — 8.12°, translating to approximately 142m of viewing width at 1000m — which makes it remarkably easy to locate and follow moving subjects.
Product Description
The VIVI Spark 8×40 binoculars are the wide-angle entry model of the VIVI Spark series, built on a classic Porro prism platform that combines 8x magnification with 40mm objective lenses. The result is the widest field of view in the Spark series — 8.12°, translating to approximately 142m of viewing width at 1000m — which makes it remarkably easy to locate and follow moving subjects.
With fully multi-coated (FMC) optics, a 5mm exit pupil and 69% light transmittance, the VIVI Spark 8×40 delivers a bright, clear image for travel, nature observation, sports events and everyday outdoor activities. The classic Porro design also produces a comfortable three-dimensional viewing experience at a budget-friendly price.
Widest Field of View in the Spark Series
The 8.12° field angle provides an exceptionally broad viewing perspective of approximately 142m at 1000m. This is the widest view of any VIVI Spark model, helping you pick up birds in flight, wildlife on the move and expansive landscapes without constantly repositioning the binoculars.
FMC Multi-Layer Coated Optics
The FMC multi-layer optical coating supports efficient light transmission and clear image quality. Combined with the 40mm objectives and 5mm exit pupil, the optical system offers a practical balance of brightness, field of view and portability for general outdoor and lower-light viewing.
One-Hand Focusing
The extra-large focusing wheel features a non-slip groove design with moderate resistance, so you can adjust focus smoothly with one hand while tracking birds, wildlife or sporting action.
Ergonomic and Portable Body
The rubber-and-plastic exterior provides a secure, comfortable grip, and at 778g the VIVI Spark 8×40 remains practical to carry on full-day outdoor trips, exploration and field observation. With an IP3 rating, the binoculars offer basic splash resistance and light rain protection for everyday outdoor use.
Why Choose the VIVI Spark 8×40?
If your priority is finding and following subjects quickly — especially birds and fast-moving wildlife — no other model in the Spark series matches the 142m field of view of the VIVI Spark 8×40. The classic Porro prism design keeps the price accessible while still delivering FMC coated optics and a 5mm exit pupil, making it an ideal first binocular for families and beginner birders.
Compared with the VIVI Spark 8×42, which uses a more compact roof prism body with IPX6 nitrogen waterproofing, the 8×40 trades a little weather protection and 143 grams of weight for a significantly wider view and a friendlier price point. If you mostly observe in fair weather and want the easiest way to spot moving subjects, the 8×40 is the better fit.
If you observe more at dawn, dusk or under heavy cloud, consider the VIVI Spark 10×50, which shares the same Porro housing but steps up to 50mm objectives for greater light intake — at 913g it is a dedicated low-light tool rather than an all-day carry.

FAQ
Are VIVI Spark 8×40 binoculars waterproof?
The VIVI Spark 8×40 carries an IP3 rating, which provides basic splash resistance and light rain protection. It is not fully waterproof and should not be exposed to heavy rain or submerged; for harsher weather, consider an IPX6 or IP67 rated model.
What is the field of view of the VIVI Spark 8×40?
The binoculars offer an 8.12° field angle, providing approximately 142m of viewing width at 1000m — the widest field of view in the VIVI Spark series.
Can the VIVI Spark 8×40 be mounted on a tripod?
The supplied specifications do not list a tripod mount; the 8×40 is designed for comfortable handheld use, and its steady 8x magnification and 778g weight keep arm fatigue low during extended sessions.
How much do VIVI Spark 8×40 binoculars weigh?
The VIVI Spark 8×40 weighs 778g, making it easy to carry for travel, hiking and full-day outdoor observation.
Are VIVI Spark 8×40 binoculars good for bird watching?
Yes. The 8x magnification combined with the series-leading 8.12° wide field of view makes it especially easy to locate and follow birds, which is why this model is positioned as an entry birding binocular.
What is the difference between the VIVI Spark 8×40 and the VIVI Spark 10×50?
Both models share the same Porro prism housing, but the VIVI Spark 10×50 uses larger 50mm objectives with 10x magnification for greater reach and better low-light performance, while weighing 913g. The VIVI Spark 8×40 is lighter (778g), wider (142m vs 114m field of view) and more budget-friendly, making it the better choice for wide-field birding and general outdoor use.
Can I use the VIVI Spark 8×40 in low light?
The 40mm objectives, 5mm exit pupil, 39.7 relative brightness and 15.9 twilight factor support comfortable viewing toward dusk, though for serious dawn-to-dusk observation the larger-aperture VIVI Spark 10×50 gathers more light.
