Zoom Binoculars
Zoom binoculars have a continuous variable magnification so you may look through them at a magnifying zoom of 8x or 10x for example. You can zoom in to any object at a higher magnification power, to get a close-up view and perceive the object in deep details.


Zoom binoculars are chosen by the magnification range they provide that is separated by a hyphen (-), for example, a pair of 10 – 30 x 25 zoom binoculars will have a magnification range of 10-30(x) with the objective lens diameter of 25 millimetres. Similarly, a pair of 12-60 x 70 binoculars will have the magnification power ranging from 12 to 60x and an objective lens with the diameter of 70mm. 

It must be pointed out that a few binoculars will have multi-magnifications, but won’t officially be called zoom binoculars. It is because the distinct magnification is achieved by switching to distinct sets of eyepieces. They can easily be differentiated from zoom binoculars as they are labelled with a slash (/) and not a hyphen (-), e.g. 25/40/70.

Do zoom binoculars work?

The idea of being capable of scanning an area and then zooming in to attain more details on a specific object sounds idyllic, but do zoom binoculars work and if they do, how well?

The answer to that question is yes they do work, but how well they work depends on various factors.

They do work and allow you to zoom into any object. Although, they cannot be compared with the image quality you get from a nice fixed magnification binocular.

The view through the variable zoom binoculars that have been tested tend to be quite fuzzy in contrast to high end mixed magnification binoculars, and they usually have a bit smaller view field. This often makes them very less suitable for uses such as bird watching or anywhere where you are required to be capable of quickly locking onto an object or scan wide open zones.

How do Zoom binoculars work?

The way that such binoculars work is relatively the reason for the view through form these binoculars being a bit fuzzy when compared to a quality fixed magnification optics. A lot of people may wonder why a digital camera’s zoom lens or a video camera’s works very well but doesn’t work like that on a pair of zoom binoculars.

The primary issue is with the binoculars’ designing zoom lenses because the binocular is nothing but connection of separated telescopes, each one of them perfectly synced so that a crisp, clear image is achieved. This issue gets far more complicated if you need a variable magnification because the zoom mechanism contains moving lens rudiments in each barrel – each telescope has to in one way or the other maintain the syncing process even at the time of zooming. To attain this, manufacturers make use of flexible linkage band that passes over the ocular arms that further connect the zoom mechanism on the right.

Advantages and disadvantages of Zoom Binoculars

There are undoubtedly advantages to zoom binoculars, but there are a few disadvantages as well.

Advantages

The most noticeable benefit is that you may have a pair of binoculars with multi magnification levels.

With this adaptability, you may instantly change from lower to mid to higher power with a simple flick of your fingertip. This is quite useful in long-range viewing conditions like during raptor migration watches, wetlands, on boats and from a lot of other non-birding activities like concerts and sporting.

When you are trying to spot a bird initially, or other wildlife, or even a player on the field, you want a lesser magnification that provides a broader view of the field. Once you have spotted your target, then you may keep zooming and use a higher magnification setting to view deeper details.

Disadvantages

So why would someone ever get a fixed magnification binoculars when they can buy zoom binoculars that offer various magnification levels?

While there are a few inherent design issues that may not be overcome in zoom bins with the use of variable magnification:

First off, if you would compare the equivalent fixed magnification 10x binocular with a zoom of 10-22 x at the 10 x, the view of the field on a fixed pair will be as much as double as widening than the zoom.

  • Reduced field of view: the image width through your binoculars will be quite less on a zoom binocular at the lower end of its magnification range as compared with that of a fixed magnification pair. It happens due to the limitation of using the moving lens part inside the eyepieces. As a basic rule, the bigger zoom, the smaller the field of view at the lower end of a range. This may be as much as half of the field of view when equated to that of a fixed magnified equipment at the same given magnification.
  • Collimation issues: collimation can be defined as the mechanical and optical alignment of a binocular and if this isn’t great it can feel like your binocular is trying to stick your eyes out. Great quality binoculars are very prudently collimated, usually with the use of laser tools. This needs time and expense at the production level and increases the rates at the retail level.

So what all this have to do with zoom binoculars? Well. Since zoom binoculars use moving lens rudiments in each of its eyepieces, every image moves quite slightly as the lens element moves to zoom. This little movement is not visible with just an eyepiece in a telescope for instance, but since you are using both eyes in a binocular, the collimation starts to change as you zoom from one side of the magnification to the other. This results in the zoom binoculars to be never in accurate alignment, so they are not perfectly collimated.

Evolution of zoom binoculars

Modern-day zoom binoculars are a pair of powerful telescopic lenses that have been adjusted to be used with both the eyes. As such, the history of zoom binoculars foes way back to the first ever built a telescope. A man from Holland named Hans Lippershey is attributed with the telescope’s invention somewhere around 17th. He wasn’t the first human to invent telescopes but was the first one to make them well known. Old time telescope comprised of a single convex lens, a single concave lens which are fixed at the opposite ends of a tube. It lets objects are magnified 3-4 times. Lippershey put two such tubes together to make a very jagged version of binoculars, but they were hard to use rightly and fell by the kerb.

The telescope was a little bit of a novelty when it was introduced, but soon a lot many fields realised its benefits. The mastermind of Italy Galileo Galilei enhanced upon its design and used his standpoint tube to study celestial bodies. With Galileo’s telescope, he became the first man in modern history to witness the craters of the moon, the four largest moons of the largest planet Jupiter, and even Saturn’s rings. Almost a century later, Sir Isaac Newton reformed the telescope by adding just a mirror. This reflector telescope opened the doors towards a modern telescope, magnifying glass, and even binoculars.

Around the same period, Johann Zahn invented the first handheld binoculars that came with the adjustable link between two telescopes. This was still a very irregular approximation of a true binocular. Earlier lenses were made up of glass that resulted in low magnification and blurry images. J.P Lemiere was the first person to invent the first actual binocular telescope in the year 1825. It found its application in U.S. Navy during the Civil War but was then replaced by the most defining invention of binoculars – the Porro Prism. It was developed in the mid-19th century.  Porro Prism flagged the way for all modern day binoculars and is still used to this day. Modern-day binoculars continue to improvise on the original designs. However, the concept of two telescopes being mounted altogether to be used with both the human eyes is over four centuries old.

How to choose a pair of binoculars

Binoculars are pricey. We would argue that you must stretch out your budget and buy the best zoom binoculars you can afford. Binoculars are long-term investment equipment that starts to pay off the day you buy them. More likely you are not going to buy new binoculars every year or so. This makes sense to choose them carefully; you must try a lot of varieties and save up for binoculars that will deliver some amazing views of the birds or whatever you seek out.

With all that said, decades of binoculars R&D by the best brands have started to trickle down in their low-priced models, and you will be astonished by the image quality you can now get from such binoculars that are priced at just a few hundred bucks($).

Picking up a perfect binocular maybe a hectic job and needs some pre-buying research. Here are six steps that you must follow to figure out where to start from while looking for best zoom binoculars:

Decide your pricing range

Top of the line binoculars provides you with a primaeval image in a comfortable, durable package. Lesser price ranges also deliver some good options, thanks to technological advancements in the last ten years. So think wisely and choose wisely before making any decision for the same.

Pick a magnification

Deciding between the 8x and 10x zoom binoculars is a personal decision. In general 10x are obviously better at distance birding. But it generally means a narrow viewing field, a little dark image even in less light, and hand-shake is easily noticeable. The 8x zoom will give you smaller image but wider, brighter, and easy for following and finding birds.

Test many models

No two birders look through binoculars the same way. The shape of the face, how you focus, size of hands, how you carry the bins while they are not being used – everything matters. So test as many pairs of binoculars as you can to get a feel of what suits you the best.

Look for crisp, bright, true colour

Image quality has superseding importance. How true is the colour? How sharp?  Are the bins bright?  Do they resolve picture details in a backlit image? Most optic stores will be better lit than your average forest.  Find a place that is dark to compare the low light performance of the product.

Pay special attention to the Crispness/Clarity to decide on image quality.

Check the eye relief

Most binoculars will have eyecups that retract to accommodate spectacle wearers or extend to provide shading for those who don’t wear any. Look for multi-adjustable and durable eyecups. If you wear spectacles, adjust the eyecups to minimum position and ensure there is abundant eye relief – you should not see a black ring around the images.

Review additional warranties and features

Pay attention to close focus and field of view, two measures that affect how much you will see. Look at the close focus and field of view to know how these factor in your decisions. Also pay good attention to waterproofing, durability, and warranty – a lot of major optics companies offer excellent and extended warranties.

Best zoom binoculars – reviews and descriptions

As with many things in life, nothing is perfect. The capability to scan for something with the use of low power magnification and then zoom into the objects to observe the close-up details over weighing their potential hitches.

Interestingly one of the major selections of zoom binoculars can be found within the category of compact size category.
