Given that there are many alternatives to choose from, getting a light gathering binocular can be a hard task. But taking that decision can be easier if you have the necessary information. That’s why we tried to showcase the most important aspects in our quick guide below, to help you make the choice.

 

Magnification and objective

The main way to classify binoculars is based on a set of numbers that have the following format – 15×80 for example. These numbers refer to the magnification power of the binoculars and the objective lens diameter. A 10x magnification power means that the image appears 10 times closer.

Choosing the right numbers depends on what you want to do with the binoculars. If you just want to watch a theatrical piece, you only need something with a range of 3x or 5x. For those looking to hunt at long distances, a power of at least 10x is needed. But keep in mind that more experience is needed to hold the device for a long time without your hands shaking. This is where a tripod comes in handy.

Lightweight binoculars for birding don’t really need a big magnification power but they require a large lens diameter. The objective (the bigger lens positioned at the front of the binoculars) is measured in millimeters. Its size has a significant impact on the overall dimensions of the binoculars and on how much light the model is able to gather.

Good light gathering binoculars should thus have a large objective. They need a lens of at least 50mm to do a good job. If you are looking for night vision binoculars, they might require an objective that is even larger than that.

 

Prism type

If you have read enough light gathering binoculars reviews you know by now that some have a sleek design while others are very chunky. That is mainly determined by the type of prism used by the binoculars. The prism is the element that vertically corrects the image, it turns it around so it’s not upside down.

The slimmer binoculars are those using a roof prism. The elements of the prism in these models are more aligned with each other, making the final product more compact. A Porro prism is one that occupies more space, but it has the advantage of providing a better image and can offer a better field of view by folding the light path.

A roof prism with the same capabilities as a Porro prism one is harder to make and that’s why two models with the same capabilities, each using a different prism, are not priced the same.

 

Exit pupil

The exit pupil is a concept that can be most easily explained as the size of the image that gets to your eye through binoculars. It’s thus the dimension of the focused light hitting the eye. Its diameter should always be at least as large as your pupil. It can be calculated by dividing the objective diameter by the magnification power number.

The average pupil dilation for a human is 4 mm in medium light conditions. An exit pupil smaller than this is thus difficult to use and it feels like looking through a peephole and not binoculars. It is thus ideal to have an objective diameter as large as possible.

 

Coatings

The most important parts of a pair of binoculars when it comes to producing quality images are the lenses and the prism. And they can all be coated with different substances that enhance their potential.

Coated lenses are the least you can expect from binoculars and it means that at least a lens has a layer of coating. An upgrade to that is the multi-coated ones. The best kind is the fully multi-coated lenses that show that each lens has been specially treated on all sides.

But the prism can be coated too and that increases the image brightness and light reflection. A dielectric coated prism is considered to be a very good one from this point of view.
