PART 71—PACKAGING AND TRANSPORTATION OF RADIOACTIVE MATERIAL. Subpart A—General Provisions. 71.0 Purpose and scope. 71.1 Communications and. Leica was the first 3. Before World War II, Zeiss Ikon was working on transforming the Contax rangefinder into a 3. Development was delayed as a result of World War II, but in 1. Zeiss Ikon produced the Contax S, the first 3. The S was not actually marked on the camera. By that time, West German Zeiss Ikon AG complained of the East German company using the Contax name, and the Contax D was branded Pentacon starting in 1. West. Some Contax D cameras sold in the United States had store brands instead of the Pentacon name. The pentaprism not only allowed for eye level viewing. It gave a corrected image just as the viewer would naturally see it. Unlike waist level viewing reflex cameras, the image is right- side up and not reversed. Besides the pentaprism, the Contax S and later Contax D (Pentacon) had a horizontal running shutter and 4. This 4. 2mm screw mount would later be used by the Japanese company Asahi in their Pentax cameras starting with the Pentax S in 1. Focus by turning the focusing ring until the image is clear. Set the shutter speed. Press the shutter release. Wind to reach the next frame. A few things we take for granted were not present, however. With an automatic diaphragm the diaphragm remains at the widest aperture until you press the shutter release. The camera then automatically stops down to the selected aperture value (f- stop). This allows you to focus and view a bright image. With the Pentacon you have to turn the aperture ring to the maximum aperture to focus and view. Then you turn it to the aperture you need for correct exposure. Only then do you press the shutter release. The standard 5. 8mm f. When you can't turn it further, it is a the correct preset aperture. No Instant Return Mirror. An instant return mirror allows for the image to be blacked out only momentarily while the shutter is released. SLR cameras have a mirror which is in the down position until the shutter is released. This allows the photographer to compose and focus the image. When the shutter button is pressed, the mirror flips up and the shutter opens allowing the light to expose the film (or today the digital image sensor). With automatic mirror return, the mirror automatically goes back down when the shutter closes allowing you to view the image again. The image is only blacked out to your eye for the moment the shutter is open. In early cameras like the Pentacon the mirror remained in the up position until you advanced the film to the next frame. In addition to advancing the film and cocking the shutter, turning the film advance knob brought the mirror back to the down position where you could see through the viewfinder again. The film advance knob in this camera was also replaced with a single stroke lever in later SLRs. No Internal Light Meter. The Pentacon has no built in light meter. Built in light meters which measured the light through the lens were generally not introduced until the 1. This camera is purely mechanical with no electronics and no battery. No Single Set of Shutter Speeds. Finally, the Pentacon does not have a single set of shutter speeds. While the camera has a wide range of shutter speeds from 1 second to 1/1. The fast speeds are from 1/5. The slow speeds are in red and the fast speeds are in black. There is a switch on the back by which you select the slow (red arrow) or fast (black arrow) speeds. You then turn the shutter speed knob to the correct speed. The Pentacon has a single knob with the lever selecting the slow or fast speeds. Other cameras like the Japanese Asashiflex models and the early Exacta models had two shutter speed knobs. By the 1. 96. 0s most SLRs had a single knob that you simply turned to the desired shutter speed. The shutter speed sequence on the Pentacon is 1/1. The modern sequence is slightly different with 1/1. I ran into a gentleman at a garage sale while I was buying an old lens. I told him I collected cameras. He indicated he had some old cameras including the Pentacon that he would like to see go to someone interested in them. He called me up latter in the day. My Pentacon came with four lenses: (1) Biotar 5. T Carl Zeiss Jena (3. Soligar 1. 35 f. 2. Berlin- Optik- Germany Nr. C Speed- Astra, and (4) 3. Suptk T 1. 57. 0. I believe they are all preset lenses. The purchase also included a Kopil Folding . The camera is in fine working and cosmetic condition. All shutter speeds appear to work and vary appropriately. I'm not sure, but the first shutter curtain may get stuck before fully opening. It makes it most of the way. The lenses look fine at least with a cursory inspection. All have caps, including some caps and a lens shade machined by the owner! The owner worked in the Praktica Industry in San Diego for many years building jet engines and knew how to finely machine Aluminum! Indeed the caps and shade he made are downright beautiful works of craftsmanship. I also bought a Kodak Retina IIc, a Yashica 4. Olympus 3. 5 ED from him. The seller was the original owner of all the items except for the Retina IIc which belonged to his dad. It was very interesting learning about the seller's personal experiences with the cameras.
