  • Celestron UpClose G2 8x21mm Roof Binoculars

    The Celestron UpClose G2 8x21mm Roof Binoculars deliver a powerful 8x magnification through 21mm objective lenses, all within a featherlight 8 oz body. This grab-and-go binocular offers a wide 378 ft field of view for tracking moving subjects at a distance and a 10 ft close focus for getting detailed views of wildlife or objects right in front of you.

    8x Magnification and Multi-Coated Bk7 Prisms

    The 8x magnification strikes a critical balance, providing enough power to see details on the sports field or identify a distant bird without introducing the hand-shake that makes higher-power compacts difficult to use. Inside, the Bk7 roof prisms and multi-coated lenses maximize light transmission, delivering a brighter and higher-contrast image than binoculars with uncoated optics. This optical system produces a 2.6mm exit pupil, suitable for daytime viewing from dawn to dusk.

    An 8 oz Grab-and-Go Compact Design

    Weighing just 8 oz (227 g), the UpClose G2 is engineered for portability. The roof prism design allows the optical path to be a straight line, resulting in a compact 69mm x 51mm x 91mm chassis that easily fits into a jacket pocket or glove box. A durable, rubber-armored coating protects the binoculars from bumps and scrapes, while its water-resistant construction ensures it can handle unexpected splashes or light rain on the trail.

    A Wide 378 ft Field of View with 10 ft Close Focus

    The 7.4° angular field of view translates to a generous 378 feet of visible area at 1000 yards, making it easy to locate subjects and follow them in motion. This wide perspective is ideal for scanning a landscape or keeping a player in your sights. For nearby subjects, the UpClose G2 can focus down to just 10 feet, allowing for detailed observation of insects, birds at a feeder, or museum exhibits.

  • What is the main advantage of the UpClose G2 8x21mm's roof prism design?

    The primary advantage of the roof prism design is its compactness. It allows the objective lenses and the eyepieces to be in a straight line, resulting in a slim, lightweight binocular that is easy to carry and hold. The UpClose G2 weighs only 8 oz, making it a perfect "grab-and-go" option.

    Are the UpClose G2 8x21mm binoculars suitable for eyeglass wearers?

    These binoculars have an eye relief of 11mm. While they can be used with eyeglasses thanks to fold-down rubber eyecups, some users with thicker lenses may find the field of view slightly restricted. For non-eyeglass wearers, the full 7.4° field of view is comfortably accessible.

    How does the 8x magnification on the UpClose G2 perform for watching a baseball game versus birdwatching?

    For a baseball game, the 8x magnification is ideal for bringing the action on the field closer without making it difficult to track a fly ball, thanks to the wide 378 ft field of view. For birdwatching, the 8x power is great for identifying birds at a distance, while the 10 ft close focus allows you to get incredibly detailed views of birds at a nearby feeder.

    With a 21mm objective lens, how well do these UpClose G2 binoculars work in low light?

    The 21mm objective lenses and 2.6mm exit pupil are optimized for daytime use. They gather enough light for bright, clear views in full daylight and overcast conditions. However, their performance will be limited in deep twilight or pre-dawn conditions, where binoculars with larger objective lenses (like 42mm or 50mm) would provide a brighter image.

    What does the 10 ft (3 m) close focus on the UpClose G2 8x21mm let me see?

    The 10 ft close focus is a versatile feature that allows you to observe subjects that are very near to you. This is perfect for activities like butterfly watching, examining architectural details on a building, or getting a magnified view of exhibits in a museum where you cannot get physically closer.

    How durable are the UpClose G2 8x21mm binoculars for hiking?

    The UpClose G2 is designed to be a durable field companion. It features a tough chassis protected by a shock-absorbing rubber armor. Additionally, they are water resistant, meaning they can withstand unexpected rain showers or splashes, making them a reliable choice for hiking and other outdoor adventures.
