I need binoculars for distance which will bring me loads of light and probably stabalised.

I live on a shipping channell and would like to be able to observe traffic.

how is the light measured in binocculars as I have noticed such a difference but dont know how it is measured. Smile

Hi

You can use exit pupil as a rough guide to image brightness, but there is no standardized method fopr comparing image brightness, since other factors, including lens coatings, optical quality and so on influence this binocular feature.

For more on the basics of bincoular design and features, see our article at
