Celestron UpClose G2 8x40 Porro Binoculars

8x40 Performance with an 8.2° Field of View

The 8x magnification strikes a critical balance, bringing subjects close without introducing the hand-shake that makes higher-power binoculars difficult to use without a tripod. The 40mm objective lenses gather ample light, producing a relative brightness of 25. This combination is ideal for a huge range of activities, from hiking to stadium sports.

What truly sets the UpClose G2 8x40 apart is its extremely wide 8.2° angular field of view. This translates to a massive 429-foot linear field of view at 1000 yards, allowing you to not only spot a bird in a tree but to follow it effortlessly as it takes flight. This wide perspective makes finding and tracking targets intuitive and immersive.

Bright Views from Multi-Coated Bk7 Porro Prisms

The classic, wide-shouldered shape of the UpClose G2 8x40 houses a Porro prism optical system, a design known for its excellent light transmission and three-dimensional image quality. The prisms are constructed from Bk7 optical glass, and key optical surfaces feature multi-coatings to reduce internal reflections and maximize the amount of light reaching your eye.

This efficient optical design is what allows the binocular to produce bright, clear images. For you, this means more visible detail on a distant athlete's jersey or the subtle feather patterns of wildlife, especially during the critical hours of dawn and dusk when animal activity is at its peak.

A 24 oz Water-Resistant and Tripod-Ready Body

Designed for active use, the UpClose G2 features a durable, rubber-armored chassis that provides a secure grip and protection from bumps. At just 24 oz, it's light enough to wear around your neck without fatigue. Its water-resistant construction ensures it can handle unexpected rain showers or splashes.

• Comfortable Viewing: Fold-down rubber eyecups accommodate both eyeglass and non-eyeglass wearers. The 12mm eye relief is sufficient for many users, though those with thick-lensed glasses may notice a slightly constrained field.
• Easy Focus: A large, smooth central focusing wheel makes it easy to adjust focus from the 19-foot close focus distance out to infinity, even while wearing gloves.
• Steady Views: For extended viewing sessions, the binocular is tripod-adaptable (adapter sold separately), allowing you to mount it on any standard photo tripod for a perfectly stable image.

UpClose G2 8x40 vs. Cometron 7x50: Field of View vs. Aperture

When choosing a general-purpose binocular, a common comparison is between the UpClose G2 8x40 and the Celestron Cometron 7x50. The best choice depends entirely on your primary use.

• Celestron Cometron 7x50's Advantage: With its larger 50mm objective lenses, the Cometron 7x50 has superior light-gathering ability and produces a massive 7.1mm exit pupil. This makes it the clear winner for low-light and astronomical viewing, where maximizing brightness is paramount.
• UpClose G2 8x40's Advantage: The UpClose G2 offers higher 8x magnification and a significantly wider linear field of view (429 ft vs. the Cometron's 357 ft). It is also lighter by 3 oz, making it a more portable and practical choice for daytime activities like sports, hiking, and travel where tracking moving subjects and minimizing weight are more important than low-light capability.
