Theyre well suited to anyone into bird watching, camping and hiking, travelling or even visiting exhibitions. Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty.
Exit pupil explained
Small Wonder, Broad Scope
This particular model offers 10x magnification and a 21mm objective lens diameter. As it sounds, 10x magnification produces an image that appears as if the user were ten 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 2.1mm, which for 10×21 binoculars is arrived at via 21 divided by 10 = 2.1 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 87 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.

Fast and easy focusing is provided courtesy of a large, centrally placed knob. The 10×21 DPC I model further sports a long 11mm eye relief for extra comfort, plus diopter adjustment to allow them to be attuned to an individuals eyesight for comfortable viewing without glasses.
