The objective or objective is an optical device capable of collecting and reproducing an image. It can be composed of one or more lenses such as mirror systems. The focal distance of the lenses is the measure expressed in millimeters that separates the lens from the focal plane. The focal distance indicates the distance between the rear nodal point of a lens and the plane on which the subjects are infinitely focused. The focal length of the lenses, however, determines the angle of view of the shot. The diaphragm is a sort of hole that opens or closes causing more or less light to enter. It is therefore necessary to set the diaphragm in order to obtain the desired effect. A very wide aperture determines a reduced depth of field but allows faster shutter speeds. A very closed aperture determines, however, a wide depth of field, with longer shutter speeds for a correct exposure.
