Product Information

Field of view: How wide the image appears, in terms of how many metres are visible at a point 1000m away. So, a field of view of 140m@1000m will take in a wider view than one of 120m@1000m.

The second problem posed by larger magnifications is a narrower field of view. While it's unlikely you're going to find a bird or other critter that won't fit in even a 12x pair of binoculars' field of view, getting that critter framed in your binoculars is another story. While it seems simple, seeing something and then raising binoculars up to your face and getting them trained on that exact thing is a skill in and of itself. Beginners often have trouble getting a bird within their binocular's line of sight, even when they can clearly see where it is with the naked eye. A wider field of view is more forgiving in such circumstances. You will get better at this the more you use binoculars. It is very common for birders to get an 8x pair as their first binoculars and then a 10x or even 12x pair as their second. Field of view – this describes how wide an area you can see through the binoculars. Sometimes it's written in degrees, but usually as a number. That number will be the width of the scene visible through the binoculars from 1,000m away. The greater the field of view, the wider the image you can see. Generally, the higher the magnification, the smaller the field of view. With a design completely devoted to being lightweight and compact Zeiss have optimised these binoculars in every respect. They have reduced the lens diameter by 2mm* which has in turn allowed for thinner lens elements to be installed. ergonomic rubber armored body design - a lightweight, ergonomic body design makes the binoculars enjoyable to hold for long periods of time. the central focus knob is intuitive to operate and is very user friendly. built to handle any environment, the binos has a rubber-armored coating to withstand extreme use and provide a non-slip grip, even in the wettest conditions. Field of View/Angle of View is the diameter of the circular viewing field. It is defined by the width in feet or meters of the area visible at a distance in yards or meters (usually 1000 yards in the USA). The angle of view is the maximum view you are capable of seeing through the binoculars expressed in degrees. You can easily convert from one measurement to the other by knowing that one angular degree is equivalent to 52.5 feet at 1000 yards. Multiply 52.5 by the angle of view to find the linear field of view. Or divide the linear field of view to get the angle of view.

Most have a central focusing wheel and a dioptre adjustment for focusing images. The dioptre adjustment is an important feature, as it only adjusts one lens and so compensates for when your eyes have slightly different prescriptions. The central focusing wheel adjusts both lenses simultaneously. Read our full Celestron UpClose G2 10x50 review for more details Best for Ruggedness What are the best binoculars?

These thinner lens elements have been placed closer together within the barrel resulting in a high-quality pair of binoculars that measure just 144mm in length and weigh only 640g. That’s up to 30% lighter than other comparable binoculars. If price isn't a concern and you just want the best optical quality on the market to date, then this pair of Swarovski CL Companion 8x30 compact binoculars are just the thing to let you observe wildlife from as close to 3 meters all the way up to 132 meters – with crystal clear vision.

Binoculars are optimized for different uses. This guide will help you understand these instruments a little better so that you can make an informed decision when choosing a pair for yourself. Refer to our best binoculars review to see which we like best and why. Step 1: What Size do You Need I would not compromise the magnification or lens size in the correct ratio. However, waterproofing is equally important for anything I have done. What type of strap do you use and why? The larger the objective lens, the more light that can get into the binoculars, and thus the brighter the image. Larger objective lenses also make the binoculars themselves larger and heavier. You'll want to find a balance between brightness and portability that works for you. Depth of Field is how much of your view is still in sharp focus behind and in front of the object. The depth of field increases proportionally with distance. For instance, your depth of field is much greater at 20 yards than it is at 20 feet. Depth of field also decreases as magnification increases. In practice, when an object moves and its distance from you changes. You will have to adjust your focus more often, or if you're looking at two objects, one might be out of focus. Best binoculars for astronomy: If you're planning on stargazing, we'd recommend a binocular size of around 7x50. The 7x magnification will work well for Astro viewing as a compromise between the field of view and magnification, while a 50mm lens will provide plenty of light transmission for spotting fainter celestial objects.

Twilight Factor is the theory that small bright images can have as much detail as large dim images. Here is the best explanation of the theory behind the twilight factor: let's say you're reading a newspaper. If you're in low light, you have to hold the paper closer (increased magnification). If it's bright out, you can hold the paper further away (decreased magnification).Affectionately called the binocular "bra," I like Cabela's Pro harness. What types of things do you do to maintain good working condition? Length x width x depth: 140mm x 118mm x 52 mm (fully opened) Warranty: 10 years Supplied with: Padded case, neoprene strap, rainguard and objective eyecups With a field of view of up to 140 meters at a distance of 1,000 meters and a closest focusing distance of 1.5 meters, the SFL 8x40 deliver a perfect overview combined with precise detail recognition. Central focusing wheel – used to bring an image into focus for both eyes equally. It should be used in combination with the dioptre adjustment. turn-and-slide rubber eyecups - turn-and-slide rubber eyecups allow users to adjust the eye-relief for a custom fit-providing a full field of view and maximum comfort during extended periods of use.

These Olympus 8×40 S binoculars are the perfect companion for observing nature, sport, wildlife and bird watching. You've probably noticed that most binoculars are described by two numbers separated by an x, 8x42, for example. That first number is the magnification (more on that in a second), and the second number is the size (in millimeters) of the objective (front) lens. The size of the objective lens largely determines the overall size of the binoculars, so that second number essentially describes their size.That first number that generally follows the model name of a pair of binoculars refers to the magnification. For example, an 8x42 pair of bins provide eight times magnification, which makes things look eight times larger. A 10x42 pair offers 10 times magnification, and so on. The second number refers to lens size. A larger lens will make the image brighter and clearer, especially in low light, but will also make the binoculars bigger and heavier (and probably more expensive)
