Exit pupil explained Click here for more info Delivers Optical Perfection, Whether Day or Night This particular model offers an 12x magnification and a 50mm objective lens diameter. As it sounds, the 12x magnification produces an image that appears as if the user were 12 times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. While for daytime use a lens diameter of 21 to 25mm is useful, for night-time viewing something between 35 to 50mm is recommended. Therefore the 50mm specification here indicates excellent suitability for low light visualisation. Also worth considering for low light work is the exit pupil. Here that is 4.2mm, which for 12x50 binoculars is arrived at via 50 divided by 12 = 4.2 exit pupil in mm, so beyond the 2-3mm which is generally thought of as being suitable for daylight use. Another thing to take into account is the field of view, which here is a wide 80.3 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation.
