Best for
A specialist low-light binocular - the 7mm exit pupil (56mm objective / 8x magnification) matches the maximum dilation of the human pupil in dim conditions, ensuring all available light reaches your eye. Popular with deer stalkers, night-watch observers, astronomy (hand-held) and anyone who observes seriously in dim conditions. Trade-off: size and weight.
Frequently asked questions
What is an 'exit pupil' and why does 7mm matter?
Exit pupil is the bright circle of light visible at the eyepiece when you hold the binocular at arm's length. 7mm matches the maximum pupil dilation of a young person's eye in darkness - meaning all available light reaches the retina. For older eyes whose pupils don't dilate as much, even 5-6mm is sufficient, but 7mm guarantees no light is wasted.
