Binoculars with central focusing have a central wheel that is able to provide perfectly sharp images. With central focus knob you adjust the focus of both barrels at the same time, moving lenses simultaneously. When choosing between binoculars with central focusing system it’s important to look for its design and performance. Depending on manufacturer, some binoculars provide sturdier focusing and some very smooth focusing, which is especially suitable for dynamic situations. Focusing throw also varies from binos to binos, it takes more time for setting a proper focus with very long focusing throw, than with the ones with shorter one. When it comes to ergonomic design, most of binoculars provide a central knob with different bulges for a better grip, very convenient when wearing gloves. Since central focusing wheel doesn’t eliminate differences in both eyes, diopter on upper side of the barrel is included.

Features of binoculars with central focusing

(+) focusing by central focus wheel and diopter
(+) precise focusing
(+) more common
(-) sometimes not fully waterproof

The name itself suggests the purpose of pocket binoculars which is to be able to store and carry them around in your pockets. They are small, lightweight, and very easy to hold in hands and carry around the neck.

They’re perfect for birding, traveling, safari, or any outdoor observations (sports events or concerts).

To ensure smaller dimensions and compactness they usually have a roof prism system that offers better optical technology and binoculars are therefore sharper. The other occurring prism system is reverse Porro.

Due to their small size, the lens diameters are between 20mm and 26mm and the magnification is normally between 8x and 12x.

With most pocket binoculars the bridge folds at two different places to bring both optical barrels together – that way they’re really compact, suitable to store in pockets and offer closer interpupillary distance.

However, in some rare cases, the bridge folds in only one place which makes them less compact. Because they are intended to be used outside they are usually waterproof and fogproof, to prevent any inside fogging when exposing your binoculars to extreme temperature fluctuations.

To keep their compactness, they have short eye relief which makes them less suitable for eyeglass wearers.

In comparison with compact binoculars, they have smaller magnifications and smaller objective lenses. But in comparison with opera glasses, they are bigger and have bigger magnifications.

However, due to their small size, they may not be the most comfortable to look through. If the barrels are too close or the focusing knob is too small they may be more difficult and uncomfortable to use.

Main Features of Pocket Binocular:

(+) easy to store in your pockets
(+) lightweight
(+) waterproof and fogproof
(+) easy handling and carrying
(+) suitable for daytime observations
(+) versatile
(-) short eye relief (less suitable for eyeglass wearers)
(+/-) lens diameter < 26 mm

Compact Binoculars Vs. Pocket Binocular

Compact binoculars:

have a lens diameter bigger than 30 mm
are more demanding to put into the pocket
are not so small.

Compact binoculars usually have only one fold, while pocket binocular has two folds.

In fact, pocket binocular is meant for those, who care the most about the appearance (small size, compactness) and not so much about the quality of observing, since it is a little uncomfortable to use it.

Compact binoculars are however much more comfortable and suitable for those who intend to take the observations more seriously. In low light conditions, none of them are doing too well.

In general, pocket binocular is almost unusable in such situations. It is very hard to use this type of binocular when wearing glasses.

Binoculars for Bird watching

People do not buy this type of binocular primarily for birding. However, this is binocular that you can always carry in your pocket and when it comes to the situation to observe, you can take that binocular out of your pocket and look through it.

Watching is usually better with 8x than 10x magnification, since binocular with 8x magnification is smaller and easier to hold.

Best Pocket Binoculars

The best binoculars are produced by the renowned European sports optics manufacturers such as:

Leica Binoculars

There are two series of Leica's binoculars- Trinovid and Ultravid. Ultravid is considered to be one of the best and Trinovid is more entry-level. Both have superior optics in a pocket format.

Ultravid is available in black and silver line and its armoring is made of black leather. Its overall appearance is truly amazing- it is extremely small and has a dual hinge design which allows the binocular to fold in two places and thus makes the binocular even smaller (when folded).

Swarovski Binoculars

As far as the Swarovski binoculars are concerned, the latter presented only one series on the market, called CL pocket. There are two configurations of them, 8x25 and 10x25, available in black, hunting-green, and sand colors.

Zeiss Binoculars

Zeiss binoculars are the latest among all mentioned above because they came on the market the last.

They claim that they are the best in this category as far as the optical performance is concerned since they were presented later than the others and so it was possible to further improve them.

They are also available in 8x25 and 10x25 and have a unique design with an interesting central bridge - the hinge is not symmetrical since the binoculars are folded so that the central focus knob is on the side.

Roof prisms

Pocket binocular is one of the smallest in the category of binoculars.

As mentioned before, they normally feature roof prisms, instead of Porro prisms. Since Porro prisms are so much bigger, their size disables them to be a part of pocket binocular construction.

Binoculars with Porro prism can never be folded as tightly as those with roof prism. This is the reason why pocket binocular rarely (almost never) features Porro prisms.

Another important thing to point out is that pocket binocular features a dual hinge mechanism.

Since size plays such an important factor, one hinge mechanism is simply out of question.

As you can see in the picture, dual hinge binoculars can be folded way closer than one hinge binoculars, which enables the user to simply store them in a pocket of a small space.

Since Porro prism are bigger, they produce brighter, sharper, and more realistic 3D images. Therefore Porro prism binoculars can have better optical performance as equally priced roof prism counterparts.

One hinge and dual hinge binoculars
