  • The History of Contax
    bayonet mount for attachment of interchangeable lenses Interchangeable lenses were available with speeds up to fl 5 The Contax also had a detachable back to accommodate the changing of film The Contax I was in production from 1932 to 1938 and by 1934 there were 12 lenses from 28mm to 500mm in the Carl Zeiss lens line As stated earlier lens coating was invented by Carl Zeiss in 1935 and application began on the rangefinder lenses in 1943 The coating was withheld as a secret of Germany until well into World War II when a shipment of coated lenses was shipped to Sweden This was the only shipment of coated lenses until after the war The Contax II began production in 1936 and added the world s first range viewfinder Shutter speeds ranged up to 1 1250 second The Contax II also had a self timer and a chromium plated body The Contax II was produced until 1945 The Contax III in production from 1936 to 1945 sported a built in light meter on top of the camera body Otherwise all of the features of the Contax II are included In 1936 or 1937 Carl Zeiss engineers began work on a new kind of camera It was to be a reflex viewing 35mm design This camera was based upon the Contax II with the addition of a mirror This design produced very dark viewing so a field lens was added still the image was too dark A fresnel lens was added along with a pentaprism to make a correct reading right to left and right side up image Focusing the lens was accommodated by turning a focusing ring on the lens By 1937 work on civilian products slowed to a stop while gunsights and bombsights took precedence It is said that work on the Contax SLR continued during lunch breaks and other personal time Unfortunately all of the Contax SLR prototypes were lost during the war The Dresden camera works were destroyed by Allied bombing on the night of February 14 1945 This bombing ushered in a difficult time in the history of Carl Zeiss Foundation At the close of the war Patton s Third Army occupied Jena and its prize the Carl Zeiss factories This action set the stage for the safe revival of the Jena works but the Treaty At Yalta decreed a pull back of the American lines to positions further west Jena and Dresden now fell under Russian occupation taking almost the entire Carl Zeiss Foundation with it The withdrawing U S Army recognized the technological importance of Carl Zeiss and assisted in the removal of 126 key management and crafts people from what was to become East Germany The relocated Carl Zeiss employees including the entire board of directors were relocated to the Contessa manufacturing facility in Stuttgart West Germany One of the first orders of business for the relocated board of directors was to officially relocate the Carl Zeiss Foundation to the Stuttgart offices Thus it was the position later that the Carl Zeiss Foundation was an entirely West German company Meanwhile in the eastern sector the Russians were claiming reparations by dismantling 94 of the remaining Carl Zeiss tooling and factories It has been said that the trains stretched for miles over a period of several months back to the motherland U S S R This relocated tooling became the Kiev camera works which produced low quality copies of the Contax and other Zeiss Ikon products for many years thereafter Even with the rape of the Dresden Jena facilities by the Russians the first component of the Carl Zeiss operation to be revived after the war were the original factories in Jena They also known as Carl Zeiss introduced a small series of cameras labeled Carl Zeiss Jena These were assembled from parts on hand and the proceeds from their sale was also confiscated as reparations by the U S S R Long term strategies for the two Carl Zeiss companies differed in that the East concentrated their efforts on their unearthed plans to produce an SLR while the West modernized the Contax rangefinders of the past At the Leipzig Spring Fair of 1949 Carl Zeiss Dresden East introduced the world s first 35mm SLR camera body with a built in Pentaprism called the Contax S The S came from the word Spiegelflex or mirror reflex but there was no engraved S on the camera There was little resemblance to the pre war prototypes in the S It had a roof prism and a 42mm screw mount for interchangeable lenses The Contax S also deviated from the older Carl Zeiss models in that the shutter was a horizontal travel cloth type to reduce the overall size of the camera In 1952 the Contax D successor to the S was again unveiled at the Leipzig Spring Fair The D appeared on the camera body and was meant to signify Dresden so as to differentiate this camera from the western Carl Zeiss The only improvements on the D were that the flash sync socket was moved to the top of the camera and the noisy nature of the S was toned down Eventually the Contax cameras of East Germany became the Pentacon meaning PENTAprism Contax It took another year for Carl Zeiss West to produce the first post war product the Contax IIa It was shown at the first Photokina in 1950 It was not until 1951 that lenses were produced for the post war Contax rangefinders Eventually there were sixteen coated interchangeable lenses for the IIa Biogon 21mm f4 5 Biotar 75mm fl 5 Topogon 25mm f4 0 Sonnar 85mm f2 0 Biogon 35mm f2 8 Triotar 85mm f4 0 Biometar 35mm f2 8 Tessar 115mm f3 5 Planar 35mm f3 5 Sonnar

  • Koni-Omega 200 review by Michael Liu
    dim light probably a complaint that one could apply to certain kinds of rangefinders the one on the Contax T is nearly impossible to focus even in the best of conditions Then again since I wear glasses I could be getting too much stray light into the eyepiece which certainly doesn t help When I tried throwing my shirt over my head to give myself a pseudo hood focussing cloth it seemed to help my view a bit Actually though I like some of the nice little details that the designers put into this camera Take for instance the design of the shutter speed and aperture controls they re laid out so that you can get equal exposures just by grabbing both rings and twisting them in the same direction i e if the exposure was say 1 60th at f 5 6 1 30 would be lined up with f 8 1 15 with f 11 etc The wind shutter cock slide is also a great idea although somewhat unwieldy compared to having to wind a knob though it s much faster and far more convenient Peter Kotsinadelis was kind enough to let me know why the Koni design incorporates three accessory shoes The one above the viewfinder is for a viewfinder eyecup The center one is for the viewfinder attachment when using the 58 60 lens they are the same lens The one on the right can be used for other reasons such as a shoe mounted flash when using the 58mm viewfinder in the center shoe Overall I m pleased with the design It doesn t take much thought to ruin your pictures but it also doesn t take much care to take pictures either After a couple of rolls of film I feel quite comfortable with the camera Of course that s all probably going to change once I get the rolls back from the developer but I ll wait until then Results Based upon what I ve heard I should be getting breathtaking photographs and beautifully toned shots I m not I can t honestly blame the camera though as this is the first time I ve used such an idiot maker of a camera i e it makes me look like an idiot Sir your darkslide is in I ve run exactly two rolls of Tri X through it guessing exposures and getting all right results but nothing I d be willing to sell Now that I have a hand held light meter I should be able to take care of the guessed exposures 120 film isn t too hard to get either so I should get off my butt and get a bunch more and burn film between naps at my desk er that s meditation sorry After all if it s just a matter of practice there s no reason why I can t get plenty of that I m honestly not concerned about the optical quality I ve talked to a

    is what inserts in to the film spool to advance the film You must remove this to gain access to the inner clutch Some newer models have a screw holding it on the older one s such as mine used solder to hold the metal piece in a slot in the end of the clutch shaft To remove it you must grasp it with a pair of needle nose and heat the tee until it pulls apart Make sure you do this on an inflammable surface and away from the solvents A mini torch which uses butane works well for this since it has a smaller flame which you can concentrate on a small area A propane torch would blast the whole clutch assembly and take longer to heat the desired area as propane burns at a lower temperature Another washer is found under the metal tee Remove it as well Here is the result Turn the clutch shaft clockwise with your fingers or pliers at the same time pulling out The shaft should come out of the chrome casing and expose three more roller pins and springs Keep these separate from the outer clutch parts and clean them in solvent Here is the clutch assembly completely disassembled showing the torch used to heat the tee solder After soaking the parts brush each part individually with a toothbrush or wire brush Hold the springs with needle nose pliers and carefully run the brush through the springs across the coils Hold the spring on one end then the other to clean both ends well I found the solvent isn t sufficient on its own to get rid of the glue like grease left behind All parts should look clean as new when done It helps if you hold the spring down on a clean piece of wood and slowly stroke the brush through Sometimes the brush will grab the spring and get caught in it Just take your time and don t lose the springs Here are the parts completely clean and ready to reassemble Note the clutch shaft and the tapered slot indicated by the screw driver It is pointing to the wider end of the slot Apply a small dab of synthetic grease at all three points around the shaft You will insert the three springs in to the dab of grease at this end first Note the small amount of grease I have placed already on the first two locations indicated below Here are two of the springs inserted in their proper locations Now place a small dab of grease at the other end of the springs Insert the roller pins in to this dab of grease with the flat end pointing in the same direction as the clutch shaft as shown below The grease acts as a glue to hold the parts together to aid in reassembly This is the trickiest part of the whole operation You must get the inner clutch assembly back in the chrome
