What the field of view of binoculars depends on?

Posted by admin on September 23, 2010


Is it the apperture size, or the eye piece size or the zoom power?

    As a general rule, the field of view will decrease as the magnification increases so a 10 power binocular will usually have a smaller field of view than a 7 power. Field of view, however, is mainly determined by optical design of the ocular (eyepiece) and rarely a function of the size of the objective lens.
