In addition, the films are more expensive than 36mm miniature films, often also the development and the deductions. APS has been displaced since the appearance of digital cameras increasingly from the market: the laity go to the digital camera, so that you also produced without any idea of ​​photographing randomly good images, the rest is simply deleted and costs nothing. For engagiete amateurs and professionals, the APS is anyway meaningless.
