  1. <p>From your description, it is not a user problem, but a problem with the indicator in the film magazine. When the camera body is cocked and the film magazine counter is on number one, the signal flag should be white. When you fire the camera, the signal flag will change from white to red. Each time you wind the the camera body after making an exposure, the signal flag in the film magazine should change from red to white. The fact that the signal flag stays red, instead of changing to white, when you wind the camera body, indicates that there is a problem with the signal flag itself. A qualified Hasselblad technician would easily be able to correct this issue.<br> David Odess<br> www.david-odess.com</p>
  2. <p>Gus, you are correct, in that the "sync contact spring", more commonly referred to as the "internal flash contact", does flex every time the shutter is fired, and, after many thousands of firings, will break. However, up until the time that it breaks, it will make an electrical connection each and every time. After it breaks, there will be no connection at all, so no flash. In my 40 years of servicing Hasselblads, I have never seen or heard of an intermittent flash problem being due to the internal flash contact, as there is never any carbon formation on the part. Basically, if the internal flash contact is not broken, it will not be the cause of intermittent flash. Once broken, there will be no flash.</p>
  3. <p>Because you aren't experiencing the problem with your 150mm lens, but only with your 80mm lens, I would suspect that your 80mm lens is the older, C type lens. If so, I would bet money that the flash terminal on your lens, (the part that you plug your flash cord plug into), is worn, which is why the shutter is only firing your flash intermittently. Unfortunately, the flash terminals for the older C lenses are no longer available.<br> www.david-odess.com</p>
  4. <p>Bill, any camera that has been sitting for 30 years will need to be serviced. If you are considering a Hasselblad "V" system (film camera), please visit my website at this link. It will tell you how to check out a Hasselblad to determine if it is working correctly:<br> http://www.david-odess.com/faq.html#q14</p>
  5. <p>The motor drive is an integral part of the camera. It is not possible to remove it and operate the camera manually.<br> www.david-odess.com</p>
  6. <p>I suspect that the light trap shield, which holds the light trap in place, was damaged, and is sticking out into the frame area. Remove the dark slide and you should see it.<br> www.david-odess.com</p>
  7. <p>Clark, I would be happy to sell you the parts for the brake assembly. Please give me a call at (781) 963-1166.</p>
  8. <p>You should find this interesting. It was taken from the "FAQ" section of my website:</p> <h3 id="q6">Why did you install or replace the brake assembly in my camera body?</h3> <p>There is a large, powerful spring in the camera body that opens and closes the rear flaps. The original 500 C bodies, made in 1957 and 1958, had an air piston (not unlike the piston on your storm door) which served as a shock absorber to absorb the shock of the flaps opening and closing. By absorbing the shock, the brake would prevent the upper flap from cracking at the axle.<br> In late 1958, the entire configuration of the gears, springs and arms in the body was modified, along with the brake assembly.<br> The new brake assembly was a vast improvement over the original brake, but problems started to develop. There was a large rubber disk in this brake, and, after years of use, the disk began to soften up and get gummy. When this happened, the flaps couldn't open and close properly and the camera would jam up.<br> In 1970 the brake assembly was modified. The rubber disk was replaced by a metal disk with a small rubber "doughnut". It worked great. It was such a good design that, to this day, I have never seen or heard of a body jamming up because of the newer type brake assembly.<br> But there was another problem. Not with the brake, but with some technicians. They didn't trust the new brake assembly. They had seen so many bodies jam up from the two previous versions of the brake that, when working on a body, the first thing they would do would be to remove the new style brake.<br> Without the brake assembly, the shock of the flaps opening and closing was transmitted to the flaps themselves. The upper flap, sooner or later, would start to crack at the axle.<br> There is no way to properly repair a cracked flap; it has to be replaced. Not only is this a pain in the neck job to do, but it is also very expensive.<br> If I replace a brake assembly in your camera body, it is because you had the older style brake. If I install a brake assembly in your camera body, it is because someone had removed the brake.<br> www.david-odess.com</p>
  9. <p>You need to replace the old brake assembly with the newer style brake assembly. I do have these in stock.<br> <br />www.david-odess.com</p>
  10. <p>In most cases, there would be no problem with swapping the front and rear lens groups from one lens to another, assuming the two lenses are the same focal length. However, if you do this, I would strongly suggest that you have the focus checked and adjusted, if necessary, by a qualified Hasselblad technician.<br> www.david-odess.com</p>
  11. <p>Kavin,<br> The CW winder will not work with the 503CX body. It will only work with the 503CXi and 503CW bodies.</p>
  12. <p>Stewart ... The filter mounting ring is held in place by the black, round serial number ring. In your case, the serial number ring is a little loose. You will notice that there are two small open slots in the serial number ring. You can use a small spanner wrench to tighten the serial number ring by turning it clockwise, and this will tighten up the filter mounting ring.</p>
  13. <p>Hasselblad never made a protective cover for the film magazines, and I have never seen such a cover made by anyone else.</p>
  14. <p>Your idea of purchasing a non-working 500 C/M would be a good idea, if you could find a "junker" at a very low cost. I do have the brake assemblies in stock, and would be happy to sell one to you. If you are interested, please e-mail me at: hblad1@comcast.net.</p>
  15. <p>The rubber disc for the brake assembly has not been available for many years. The reason for this is that the brake assembly was modified around 1970, as the rubber disc started to soften after a number of years, and created problems with the operation of the camera. I would strongly suggest that instead of trying to replace the rubber disc with another piece of rubber, that you purchase the updated brake assembly.<br> <br />www.david-odess.com</p>
