Istilah ''prime lens'' pada awalnya mempunyai arti '''lensa utama''' pada sebuah kombinasi sistem lensa.<ref>{{cite book|title = The British Journal of Photography|publisher = Liverpool Photographic Society|year = 1967|edition = v.115|url = http://books.google.com/books?id=ZIAqAAAAMAAJ&q=prime-lens+date:0-1950&dq=prime-lens+date:0-1950&lr=&as_brr=0&ei=M-WvR5rJJ5aytgOZsuSDBg&pgis=1 }}</ref> Ketika sebuah lensa digunakan bersamaan dengan misalnya ''teleconverter'', lensa tersebut sering disebut ''prime lens'' yang berarti lensa yang utama, dan ''teleconverter'' sebagai komponen tambahan ([[bahasa Inggris|en]]:''auxiliary'').
