Frequently asked questions

Are 7x35 binoculars good for bird watching?

They suit all-round birding in woods and backyards. The 5 mm exit pupil stays bright at dawn, dusk and under trees, and 7x keeps the view steady and the field wide enough to find moving birds. For most backyard birders an 8x42 remains the default.

What does 7x35 mean?

7 is the magnification, so a bird looks 7 times closer. 35 is the diameter of each objective lens in millimetres, which sets how much light comes in. Dividing 35 by 7 gives the exit pupil of 5 mm, the width of the light beam reaching your eye.

How bright are 7x35 binoculars?

Relative brightness, the exit pupil squared, is 25, against 27.6 for an 8x42 and 17.6 for a 10x42. Twilight factor is 15.65. Coatings and glass quality change real-world brightness a great deal, so two 7x35 binoculars at different prices can look very different at dusk.

7x35 or 8x42 for birding?

Compared with an 8x42, a 7x35 gives a wider, steadier view in a lighter, smaller body with less light. Try the numbers in the binocular calculator to compare directly.
