Resolution

Another term used in connection with photography and binoculars is “resolution“, which is a measurement of the binoculars’ ability to distinguish fine detail and produce a sharp image. Better resolution also delivers more intense color. The size of the objective lenses of a pair of binoculars has a huge impact on resolution (the larger, the more light is gathered, resulting in more detailed images delivered to the eyes). However, big objective lenses will mean nothing if  the quality of the optical components, the type and quality of the optical coatings, atmospheric conditions and proper optical alignment (collimation) is not of good quality. Nowadays top-of-the-range compact binoculars deliver detail as good as larger models, in spite of their smaller apertures.
