As it sounds, 8x magnification produces an image that appears as if the user were eight times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. For daytime use a lens diameter of 21 to 25mm is ideal. Also worth taking note of is the exit pupil. Here that is 2.6mm, which for 8x21 binoculars is arrived at via 21 divided by 8 = 2.6 exit pupil in mm, so in line with 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 112 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 2.2 metres.
