Key specs – 8.5x magnification; 42mm objective lenses; 7.6° field of view; 20mm eye relief; adjustable eye cups; 1.5m close focusing distance; 974g (with strap and lens caps)

In summary, then, an 8×42 pair of binoculars magnifies a scene 8x and has 42mm lenses; a 10×25 pair has 10x magnification and 25mm lenses. Should I care about features such as prism types or ED glass? If you want the binoculars for walking around and using them freehand, you want a binocular that is easy to handle, lightweight and as small as possible, and if possible with a strap or with the option to attach it to your binoculars. Prisms: These flip the image right side up within a lens; without them, images would come through upside-down. Prisms also shorten the optical path, resulting in closer images. There are two types. Porro prisms are inexpensive but often only fit in larger binoculars, since the eyepiece is offset from the binocular tube to allow more room for prisms to flip the image on the way to your eye. Roof prisms make for slimmer binoculars, but they’re usually more expensive due to their more complicated manufacturing, allowing the prism to align with the eyepiece and the binocular tube.

Not compatible with #93648 Off-Axis Guider, not compatible with #93519 2" Mirror Diagonal (discontinued) Binocular product descriptions use terminology exclusive to optical lenses. Here are the most common words and phrases you’ll come across. Key specs – 8x magnification; 42mm objective lenses; 8.12° field of view; 17mm eye relief; adjustable eyecups; 2m close focusing distance; 729g (with strap and lens caps) My only complaint is that the focus adjust wheel is a little stiff and needs a fair bit of effort to shift. Oddly, the diopter adjustment wheel, which is handily located just behind it, is far easier to tweak. The Celestron UpClose G2 10x50 is about as basic a pair of binoculars as you can get. The Celestron brand makes many different models of binoculars, some exceptionally high-end, but this pair of 10x50s represents the most affordable available.

Nitrogen filling prevents fogging while the design is slim and simple. An extendable eye relief provides comfort for spectacle wearers, as do a dioptric adjustment ring, flip-down lens cap, and a new strap mount. A 15-year warranty provides extra peace of mind.

This means that for your hobby or subject, it's worth thinking about what the best combination of magnification of objective lens size will work for you. Compact, mid and full-size options in roof or porro prism from 10x to 20x provide multiple options for your adventures.

Binoculars: Perfect for hunters who need to be able to see long distances and sometimes use rangefinders for distance and night vision. This high power binocular with a 20 level magnification allows you to see great details as well as better quality lenses and you can use them in the morning and at night, as you need with the same results. As previously mentioned, the larger objective lens size on the 10x50 binoculars allows for them to offer brighter images. Even in low-light conditions you can expect these binoculars to perform exceptionally well. However, this does not necessarily mean that they offer the highest possible quality. This is largely dependent on the model of binoculars and the glass that they use. The Nikon Prostaff P3 binoculars are entry-level and we were really impressed when reviewing them. Nikon has saved on manufacturing costs where it counts, mainly in the accessories that these binoculars ship with, but has retained the high-quality optics that I expect to see in a Nikon product. Normally we wouldn’t recommend using a pair of 12x magnification binoculars without a tripod but with stabilisation these work just fine, and are optically splendid. They present a sharp, bright image right out to the very edge of your field of view with neutral colour representation.This binoculars has a 20x magnification and a 50 mm objective lens, which will allow you to have the sharpest image; thanks also to the BK-7 prism material and InstaFocus focusing system.
