Frequently asked questions

Are 8x32 binoculars good for bird watching?

They suit light, all-day birding. The 4 mm exit pupil is comfortable in most light but dims under heavy canopy, and 8x keeps the view steady and the field wide enough to find moving birds. For most backyard birders an 8x42 remains the default.

What does 8x32 mean?

8 is the magnification, so a bird looks 8 times closer. 32 is the diameter of each objective lens in millimetres, which sets how much light comes in. Dividing 32 by 8 gives the exit pupil of 4 mm, the width of the light beam reaching your eye.

How bright are 8x32 binoculars?

Relative brightness, the exit pupil squared, is 16, against 27.6 for an 8x42 and 17.6 for a 10x42. Twilight factor is 16. Coatings and glass quality change real-world brightness a great deal, so two 8x32 binoculars at different prices can look very different at dusk.

8x32 or 8x42 for birding?

Compared with an 8x42, a 8x32 keeps the same magnification in a lighter, smaller body with less light. Try the numbers in the binocular calculator to compare directly.
