Fixed focus lenses are lenses that are fixed to be perfectly focused when it is placed at a specific distance from its subject.unlike traditional lenses,fixed focus lenses can't be adjusted or manipulated(as the name implies).generally,fixed focus lenses are wide angle lenses that are locked on smaller aperture settings so that the camera can take picture of a variety of subjects.
Given these fixed parameters,fixed focus lenses allow photographers to take picture of subjects,ranging from landscapes to people to animal,as long as the camera is within the appropriate depth of field.
Fixed focus lenses work best when they are located at least six feet away from their target subjects.in fact,the general range at which fixed focus lenses can be effective ranges from six feet to infinity(of course,with infinity being the oretical endpoint).
Although simpler,less expensive are usually equipped with fixed focus lenses,some higher end cameras may also come with fixed focus lenses to help a professional photographer create highly refined shots.
