In film and photography, a prime lens is either a photographic lens
whose focal length is fixed, as opposed to a zoom lens, or it is
the primary lens in a combination lens system.
Confusion can sometimes result due to the two meanings of the term
if the context does not make the interpretation clear. Alternative
terms primary focal length, fixed focal length, and FFL are
sometimes used to avoid ambiguity.
