Product Description

This second generation Celestron 8 x 40mm UpClose G2 is a very inexpensive all-purpose porro prism binocular with good-sized 40mm objective lenses that gather a lot of light for bright, clear images. It is great for watching sporting events, to take on vacation trips or camping, or to take birding or out to the lake on weekend outings.

The 8x40mm UpClose G2 has a wide 8.2° field of view (430' at 1000 yards) and very fast focusing so you can see all the action and keep fast-moving action sharply in focus. It's rubber armored for a comfortable grip and weather-resistant to shrug off the occasional summer shower (although it is not waterproof). Its 40mm fully coated BK7 optics gather substantial amounts of light, giving it a twilight factor of 17.89, thus making it a useful performer in the low light of twilight or under overcast skies.

Close focus is 16', making it a reasonable choice for backyard birding. Usable eye relief is 12mm, so there will be some vignetting for those who must wear eyeglasses while observing. Overall, this is a good medium power/wide field binocular at a sensational price - easy on the eyes, easy in the hands, and very easy on the budget.

Features of this binocular . . .

  • Porro prism optics. Traditional porro prism design using BK7 prisms. Center focus.
  • Fully coated optics. The optics are treated on all air-to-glass surfaces with antireflection coatings for good light transmission and multicoatings on critical optical surfaces.
  • Weather resistant. O-ring sealed to resist showers and inclement weather, although not designed to be fully waterproof and fogproof.
  • Armor. Black rubber armor absorbs noise and shock and provides a good grip when wet. Molded-in ridges for a secure and comfortable grip.
  • Roll-up eyecups. The shallow rubber-rimmed eyecups roll down for eyeglass or sunglass use.
  • Close focusing. Focuses to 19', making it more suitable for sporting events and long distance viewing, rather than close-in birding and butterfly watching.
  • Very fast focusing. Less than a third of a turn of the large ribbed focus knob moves from the 19' close focus out to the horizon so you can keep track of fast-moving action.
  • Rotary diopter correction. A variable diopter ring on the right eyepiece allows you to match the binocular optics precisely to your individual eyesight for a sharp image.
  • Tripod adaptable. For extended no-hands observing, a protective cover on the center hinge unscrews, revealing a 1/4"-20 thread hole for mounting the binocular on an optional photo tripod using an optional tripod adapter.
  • Standard accessories. A neck strap, eyepiece and lens covers, and a soft nylon carrying case with shoulder strap are standard equipment.
