8x42 means 8x magnification and 42 mm front lenses.
A subject looks 8 times closer than with the bare eye. Each front lens is 42 mm across; a larger lens gathers more light and adds weight.
The exit pupil is 5.3 mm (42 divided by 8). That suits dusk, dawn and night use: Nikon puts the eye's pupil at about 7 mm in the dark and about 2 mm in daylight.
A 42 mm front lens makes it a full-size binocular. 8x is within the 10x the British Astronomical Association gives as the limit for hand-held use.
The chart holds 75 8x42 models with a median view of 393 ft and a median weight of 24.2 oz: every 8x42 binocular compared.
