Binoculars

Everyone likes to get gifts, but some gifts are better than others. Sure, you pretend to like the malodorous cologne or the ugly sweater, but then they get tucked away somewhere until they eventually get thrown away. But binoculars make great gifts because everyone can use them and they can last a lifetime. Depending on one’s needs, decent binoculars can be had for less than $50 or they can cost several thousand dollars. There’s something for everyone.


Buying binoculars can be confusing because there are so many different models to choose from. And sometimes it’s hard to know what all the specifications mean. So let’s clear up the confusion and go over a bunch of binoculars that cover a wide price range.

The size and shape of a pair of binoculars is determined by the type of prism in them. The prism used to present an image right-side up and laterally correct. There are two types of prisms: roof and porro. The glass elements in a roof prism are in line with one another, making roof-prism binoculars more streamlined and easier to hold. In porro prisms the glass elements are offset from one another, providing a longer depth of field and a wider field of view, but at the expense of a bigger, heavier design.

Another feature to consider is magnification power. Everyday binoculars should be between 7x and 10x power. Theatergoers should choose 7x, while big-game hunters would need 10x or higher. Anything higher than 10x is very difficult to hold steady without a tripod. When you see binoculars specified as 7x20, the “7x” means that they make things look seven times closer than with the naked eye and the “20” means that they have an objective diameter of 20mm. The larger the objective diameter, the more light gets through.

The objective diameter also determines the exit pupil diameter, which should always be larger than the pupil of your eye. The pupil of a human eye ranges from about 1mm in bright conditions to about 7mm in the dark. A binoculars’ exit pupil diameter is determined by dividing the second number by the first. In the case of 7x20, the exit pupil diameter equals 20/7, or 2.85mm.

A binoculars’ angle of view determines how much of a scene you can see. In other words, say you were standing in the center of a pie looking out toward the crust; the angle of view would determine, in degrees, how wide a slice of the pie crust you could see. The angle of view, combined with the magnification power, determines the field of view. As an example, a field-of-view of 330 feet at 1000 yards means that you could fit into view the entire body of an airplane that’s 330 feet long when it’s 1000 yards away.

Good quality binoculars should also contain high-quality lenses with coatings that suppress glare and preserve color fidelity. The inside cavity of good binoculars should be filled with nitrogen to prevent fogging. They should also be waterproof and dustproof. Let’s take a closer look at some good-quality binoculars at various price points. We’ll cover them in price order.

LaScala Optics 7x18 LS Sparrow

If you’re looking for an inexpensive pair of binoculars that perform well for the price, then consider the LaScala Optics LS Sparrow 7x18.
