Ultra Compact Binoculars For Everyday Use

small binoculars Ultra Compact Binoculars For Everyday Use
Rich Russell asked:

Binoculars have become more and more popular over recent years, having many uses in a range of outdoor recreational activities and pursuits. If you are going hunting, camping, hiking, fishing or sailing, a pair of binoculars can add a new dimension and in some cases could be an essential piece of equipment. But could ultra compact binoculars do the same thing for our everyday lives?

Only a few years ago, it would have seemed ridiculous to suggest that we wouldn’t consider leaving the house without taking a phone with us. And yet now, carrying a cellular phone has become the norm and it seems strange not to have one. They seem to grow in sophistication on an almost weekly basis, with improved cameras, music players and software. What was once a toy for the techno geek is now mainstream.

Binocular technology has also advanced, particularly in the area of compact binoculars. Some of the models that are available now look very different from the larger, more traditional designs. They look modern, sleek, stylish and very, very small. The newer ultra compact binoculars would easily fit into a purse or shirt pocket and are just as easy to carry around as the ubiquitous cell phone.

Small size doesn’t equate to low quality though. It is now possible to get very good optics and quite high magnification in a very small package. They won’t break the bank either with prices comparing very favourably with some of the other technology that we carry around. So what use would we city dwellers make of these shiny new devices?

There are obvious uses such as at sports events such as football games, horse racing or track and field. But what about indoor sports like basketball or ice hockey. There is also the theatre, ballet and opera. These modern devices are just as unobtrusive to carry around, and of far better quality than traditional opera glasses.

These devices are not just for viewing objects at great distances. They can also have a very short minimum focusing range, enabling you to better appreciate the detail on object that is quite close. From taking a closer look at the ornate carving on the walls of a building, to picking out the finer points of a painting or sculpture in a gallery, compact binoculars can enhance your viewing pleasure.

And, let’s be honest, it’s not all about the pursuit of culture, binoculars can just be fun. Who doesn’t like to people watch from time to time? When you leave the gallery, you can find a pavement café, drink a coffee and watch the world go by. And if something interesting seems to be happening on the other side of the square, you can zoom in for a closer look. Go on, you know you want to.

We have become accustomed to being able to carry our entertainment around with us. With developments in ultra compact binocular technology opening up new possibilities for fun on the move, could they become the latest ‘must have’ accessory? They are certainly available at prices to suit most budgets without stinting on quality. Will you be ahead of the trend?

How to Buy Binoculars

Benjamin Hauck asked:

Binoculars are an excellent tool to help bring the action up close and personal, whether observing birds in a nature preserve, football players in a stadium, or your favorite rock star at a concert. Yet different uses require different types of binoculars. With hundreds of different models to choose from, it can be difficult to figure out the best pair to buy. Yet with the understanding of a few basic concepts, choosing a pair of binoculars can be made much easier. Let’s take a look at some of the most important concepts when choosing a pair of binoculars.

Magnification – Magnification is the first number in a pair of binoculars. So when you see a pair of binoculars labeled as a 10×50, the magnification is 10x, or 10 times. That means that the binoculars will make the object appear 10 times closer.

So is more magnification always better? Not necessarily. When you increase the magnification, the object will appear closer, but the image will shake more due to the magnification and the field of view will get smaller. Most binoculars are between 7x and 10x. As a general rule, if you are going to be closer to the subject, choose a lower magnification. If you are further away, choose a higher magnification. So if you have excellent tickets to your favorite football team, go for something in the 7x range. If you are a bit higher and further back, then choose a higher power around the 10x range.

Aperture – Aperture is simply the size in diameter of the front objective (in millimeters). The front objective is the lens (usually glass) in the front of the binoculars. If you look at our example of the 10×50 binoculars, the aperture is the number 50. So the 10×50 binoculars have a magnification of 10x and an aperture of 50mm. The bigger the aperture, the more light the binoculars will gather and the brighter the image will be. Also, a larger aperture will provide greater resolving capabilities providing greater detail. However, a larger aperture will also make the binoculars larger, heavier and more expensive.

So what is the best size to choose? Think about where and when you will be using the binoculars. If you are using the binoculars in a low light situation, such as at nighttime or in a darkened theatre, then go for a larger aperture in the 35mm to 50mm range. If you will be in daylight, then you can do fine with something in the 20mm to 35mm range.

Also make sure to think about portability. If the binoculars have to go into a purse, pocket or other small area, then go with a smaller aperture in the 20mm to 30mm range. If portability is less of a factor, then a full size pair in the 35mm to 50mm range will provide a brighter, higher resolution image.

There are a number of additional concepts and specifications for binoculars, but magnification and aperture are the two most important. Understanding these two factors can make choosing a pair of binoculars much easier. So whether you are looking for binoculars for hunting, sports, birding, boating or any other use, you are now that much closer to finding the right pair of binoculars.

Binoculars For Military Uses

David Faulkner asked:

You do not need any license for military binoculars like you would for any other military supply. it does not matter if you get them foe a gift or for your own use you can make sure that you are getting a binocular set that will give you the features you want by what you intend to do with it. It is so important to know what you need to find that pair of binoculars. The use of binoculars will be something that the military or anyone who loves to work in secret conditions will need to consider. The more you pay for them, the better the binoculars you will get.

If you are searching for a pair of binoculars that will bring everything right in to you so that you can see what is going on or for completing those military missions that require you to have tact and skill, you will need to understand what the numbers mean. If you will take a look at the titles that =re on the different binocular brands, you will notice that they all have numbers like 9×30 on them. The first number tells you what the magnification is. The nine would be nice times the magnification that it was before. The 30 would tell you that the lens is thirty millimeters across from one side to the other. It is a reminder of just what the pupil of a human eye does. The larger and wider it opens up to get lighter the better your vision will be in low to dark situations.

How to Pick a Good Pair of Binoculars

Matt Seweryniak asked:

Binoculars aka field glasses are like two telescopes pointed at the same area. It is easy to perceive depth because it has two lenses and not just one, like a monocular.

The binoculars have been around since about the 17th century after telescopes have been invented. People use to mount two telescopes side by side and looked through them with both eyes.

Between the 1850-1890s, a prism type of binocular was invented that allowed greater depth perception by allowing the eye pieces to be spaced wider apart. These binoculars allow greater magnification.

The most affordable binoculars are porro prisms that allow for brighter images and are precise instruments. These binoculars are wider and sometimes need to be re-aligned.

An expensive kind of prism binocular is the roof prism binocular. This binocular is smaller and narrower but loses some brightness. The good think about them is that they usually never have to be re-alligned. They are also much lighter. Optical coating fixes this problem. That is why many roof prism binoculars are coated.

Optical Coating is a great feature that helps make a brighter image by reducing the amount of light that is reflected. Reflected light inside the binoculars makes the image hazy.

General Binoculars are focused by moving a round wheel that focuses both telescopes at once. More sophisticated binoculars use independent focus which means that each side of the binocular needs to be adjusted individually.

Some binoculars have image stabilization technology which dampen sudden movement. It can usually be turned on or off by the user. This means that very high powered binoculars can be hand held when normally they couldn’t. The image quality is not always as good for stabilized binoculars, and they are usually more expensive.

Coin-operated binoculars are very popular in many tourist attractions. They allow a more detailed view. These are always mounted on a pedestal and are usually high powered.

Military Binoculars are usually hand held and at a magnification of 5x or 7x. Military binoculars are more rugged and sturdy than regular binoculars and they also use independent focusing because it is more sturdy than central focusing. Most military binoculars also have special features that help it work when wet or to block out laser beams. Sea binoculars are meant to be easier on the eyes because of the sea rocking back and forth.

Astronomical Binoculars allow people to view certain elements of the sky from far away. There are many moons and planets that can be viewed with binoculars. Pluto, Eris and Uranus can all be seen easier with the use of binoculars. Some users use lower magnification binoculars so they can have a larger field of view than if they used a higher magnification.
