Product Information

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. x 70 = very nearly as bright as the 10 x 50, and will show more detail. But only some people will be able to hand hold these due to the high level of magnification and the weight. As you shop for binoculars, you’ll see that each pair has a spec listed in this number x number formula. The first number in this equation indicates the magnification power that the optics provide. The second number indicates the objective lens diameter for the binoculars. These numbers, taken individually or together, can tell you a lot about the viewing quality of that particular model. Magnification

Metal Supplies™ have been supplying the UK building and construction industry with all types of structural steel for many years, including a wide range of Mild Steel Steel Hollow Sections: square, rectangular and circular. The listed magnification power (the first number in the formula) indicates how many times larger an image appears through the ocular lenses than it does with an unaided eye. In the case of the formula 20×50, a pair of binoculars with this magnification would produce an image that is 20 times larger than what you would see with your eyes alone.

Decent level of magnification and can be hand held my many people. A binocular’s objective lens diameter (listed in millimeters) shows the width of the front lenses (the side closest to the object being viewed). These lenses are used to gather light photons. Our eyes use light photons to see. As an objective lens gathers light, it provides a clearer, sharper image. The wider the lens, the more light that can be gathered. Our collection of 20 x 50 house plans include all types like simplex, duplex and triplex. You can choose from a wide range of styles and professionally designs floor plans.

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.

A pair of 20×50 binoculars will magnify 20 times and employ objective lenses of 50mm diameter. These binoculars will provide an exit pupil of 2.5mm (objective lens divided by magnification). An exit pupil of this size provides plenty of daylight power with decent cloudy or late-afternoon visibility. You might want to add a tripod for stability, however.
