When shopping for binoculars, you’ll often see them labeled with two numbers, like 8x32 or 10x50. These numbers aren’t just random—they tell you crucial information about the binoculars’ capabilities.
Magnification Power (First Number)
The first number in the sequence, like the "8" in 8x32, indicates the magnification power. This tells you how much closer the object will appear compared to viewing with the naked eye. For example, with a 10x50 pair, objects will appear ten times closer. While higher magnification can bring distant objects closer, it can also make it harder to keep the image steady and narrow the field of view.
Objective Lens Diameter (Second Number)
The second number, like the "50" in 10x50, refers to the diameter of the objective lens in millimeters. This lens gathers light and sends it to your eyes, so a larger lens means more light can enter, resulting in a brighter image—especially useful in low-light conditions like dawn or dusk.
Understanding the Relationship Between Magnification and Lens Size
The ratio between these two numbers is key to getting a clearer and brighter image. For instance, 8x42 binoculars will generally offer a brighter and sharper image compared to 8x32 or even 10x42 binoculars, due to the larger objective lens.
Choosing the Right Pair: What to Consider
- Magnification: For most outdoor activities like bird watching or wildlife observation, a magnification of 7x or 8x is ideal. Higher magnification can be useful for stargazing but may not be practical for tracking fast-moving objects like birds due to the narrower field of view.
- Objective Lens Size: Larger lenses are great for low-light conditions but keep in mind they also add weight. Consider how and where you'll use your binoculars when deciding on the lens size.
