    Here are some important points about these 8 power binoculars:

    • 8 Power Magnification: The "8x" in 8x42 indicates the magnification power, which means the object you're looking at will appear eight times closer than it would with the naked eye. In comparison, 10x42 binoculars provide a higher magnification of ten times. However, higher magnification also means a narrower field of view and what is perceived as reduced stability. Remember if your hands tremble a bit, the trembling will be magnified by as much as you are magnifying the image. 
    • 42mm Aperture: This very popular aperture gives extraordinary light gathering power and very high resolution, but maintains a size and weight that is not too big or heavy to carry all day in the field. 
    • Wide Field of View: The wide field of view in 8x42 binoculars allows you to see a larger area of the scene you're observing. This is advantageous where you want to scan a broad landscape, and follow movement in sports, or in the natural world with birds and other wildlife.
    • Increased Stability: Higher magnification binoculars like 10x42 can be more challenging to hold steady due to their stronger magnifying effect. Even slight hand movements can cause image shake and reduce the overall viewing experience. The lower magnification of 8x42 binoculars provides more stability, making it easier to achieve a steady image.
    • Comfortable Exit Pupil: The exit pupil of the eyepieces of a binocular is measured in millimeters, and is easily seen if you look at the eyepieces with light passing through the binocular, the exit pupil will appear as a disc of light usually in the middle of the eyepiece. Small exit pupils (e.g. 3mm or less) require that your eyes “lock” onto the exit beam of light to see the image coming through the binoculars, which will eventually cause some eye strain. Large exit pupils (e.g. 5mm or more) make it easy to center your eyes over the exit beam of light, thus making it more comfortable for you to see the image coming through the binoculars.
    • Better Image Brightness: When comparing two of different magnifications (e.g. 8x42 vs. 10x42) of binoculars that are made with the same glass types, same coatings, same aperture, same prism types, etc, the Twilight Factor is better at 8x42 than for 10x52, which means that the image would be brighter at 8x. More brightness in the binocular is highly desirable if you are observing in low light conditions.
