The Penti was manufactured in Germany from the East by Welta from 1959. It was available with red, black or blue body. Once the optical industry of East Germany introduced a system load 35mm film in parallel with the West German film Agfa Rapid. This system SL (SL-System = Schnell-Lade-System: Fast Load System) uses two identical cartridges, one charged and the other empty. The film feed system shifted the film through the plane of the image from one cartridge to another, image by image. The Penti may have been the best compact camera for this charging system film, a camera viewfinder with a complete set of controls for manual adjustment, all as rings around the target: one for the distance, one for opening and one for shutter speed. You can make 72 exposures 18 × 24mm on a 35mm film strip. There was an Objective 1: 3.5 / 30, a Domiplan Meyer or Meyer Trioplan, and a shutter blade synchronized with the flash (The timing was adjusted only for flashes of light bulb!). His specialty was the forward button long movies. Once inserted into the camera, the film is advanced to the next frame. After exposure, the button reappeared along its entire length, so that the neglect of the film advance was never a problem with this camera. You can see the button pushed in, pictured back up. The Vitessa Voigtländer had a similar feature.
