Exit pupil explained Click here for more info Delivers Optical Perfection, Day or Night This particular zoom model offers a 10x to 30x magnification and a 25mm objective lens diameter. As it sounds, up to 30x magnification produces an image that appears as if the user were 30 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 ideal. Also worth considering for low light work is the exit pupil. Here that is 2.5 to 0.8 mm, which for 10x25 binoculars, for example, is arrived at via 25 divided by 10 = 2.5 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, due to the zoom capability, is 56-33 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation. Closest focusing distance is five metres.
