Films for the Porst reflex CX4
The Porst reflex CX4 requires 35mm films. These are still easy to get today and development services are still around. Possible films for this model are the Fujifilm Superia 200* for color pictures and the Kodak T-Max 100* for black and white photos.
The 35mm camera has a thread for a tripod. In addition, there is a connector for a cable release and a self-timer.
The Porst reflex CX4 is no longer produced. The condition of the camera and whether it still works is today the main factor on the value of a used copy of the camera.
