UpClose G2 8x40mm Porro Binoculars
UpClose G2 also contains other optical surfaces treated with special coatings to boost light transmission even more. The result is a brighter view than uncoated binoculars.
Coatings and Prisms
Inside the UpClose G2 are two Porro prisms, reflective optical prisms that the form of a right-angle triangle with two sides of equal length. Porro prisms make binoculars more compact without compromising focal length or the dispersion of the light rays as they pass through it giving the classic “broad-shoulder” shape of a traditional binocular. Our Porro prisms are constructed of BK-7 optical glass, which provide high reflectivity so that more light passes through the optical path to your eye.
The Body
Whether you are out on the trail or inside a crowded stadium, you want a binocular that is comfortable to hold and use over long periods, without fear of bumps or drops. UpClose G2 features a lightweight and durable armor-protected chassis. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. The UpClose G2 is also water resistant and can repeatedly stand up to unexpected conditions.
Viewing through UpClose G2 is comfortable for eyeglass wearers and non-eyeglass wearers alike, thanks to its rubber eyecups. Keep the eyecups up for proper positioning of the eyes without glasses. If you are wearing glasses, simply fold them down and out of the way
