Opening your eyes to binocular magnification can help you achieve the best views possible. In these situations, it could be best to opt for a set with a lower power. Too much magnification can fill your lens and make it difficult to make out your object. In addition, if viewing closer objects, a higher binocular power can zoom in too much. “A lower magnification will help you see whatever you’re looking at much better because it’s not going to magnify all those natural shakes that we have in our hands and our arms,” Hamilton says. For example, if you’re glassing without bracing your binoculars, you can risk moving too much for a clear picture. A higher magnification can also magnify your movements, which can affect your vision, according to Hamilton. Not every magnification power can suit every outdoorsman. “When you’re in a more vast, open landscape, for example, that’s where you may want to start looking at a binocular with a higher magnification, like 10, 12 or maybe even 15 or 18.” BIGGER ISN’T ALWAYS BETTER “You’re going to want to choose a lower magnification range, like 8- or 10-power binoculars, when you’re in an area of the country that’s really heavily wooded or dense foliage and you’re not going to be able to glass that far to find an animal,” Hamilton says. Try to envision the landscape of your favorite hunting spot.
#BINOCULAR STRENGTHS CRACKED#
You’ve now cracked the equation, but what is the right combination for your needs? To determine your best binocular strength and objective lens diameter, look at your primary location. So, an 8×42 binocular will have an exit pupil of 5.25 millimeters. Divide the objective lens diameter by the magnification power.

This can compromise how easily they’re packed, held or used.īONUS PRO TIP: You can determine your binocular’s exit pupil size with a quick equation. However, larger lenses can add weight to the binoculars themselves. A larger objective lens can allow more light to pass through and create brighter, sharper viewing conditions. So, a binocular with “42” listed for its objective lens will have two lenses 42 millimeters in diameter. While binoculars have two objective lenses, each is the described diameter.
The objective lens diameter is the second number in the equation.
“So, any image I see through these is going to be magnified eight times,” Hamilton says. For example, an 8×42 binocular carries a magnification of 8 power. To begin, binoculars are identified by their power and objective lens diameter. Use these optics Pro Tips during your next outing and get your sight right. But which binocular configuration is necessary to achieve that perfect picture? Vortex Optics’ Chief Media Ambassador Jimmy Hamilton has a quick overview to help you better understand binocular magnification. Whether panning over your hunting ground or capturing a glimpse of a passing bird, binoculars can be great optical tools.
