bueh Posted January 4, 2007 Share Posted January 4, 2007 I recently got two new (used) wide angle lenses for the M645 system. Both have the same problem: The rear of the lens (where the bayonet is) has a little bit of play -- it's not perfectly fixed/solid as my other M645 lenses. The part of the bayonet moves a tiny little bit around, less than 1 millimeter, but this shouldn't be normal -- I didn't order a tilt/shift lens! This means that the lens sits rather loose on the camera body when mounted. It also clanks a little bit when moved, so it is pretty obvious that the bayonet fixing is not rigid. All screws I can see are very tightly screwed in, so those don't seem to be the problem. Has anybody else experienced this kind of problem and knows if this can easily be fixed by myself? Given the hourly rates of photo repair people I hesitate to give them to the local "camera clinic" if the lens has to be taken apart. I can probably return the lenses, but since this seems to be not a one-time problem, I would like to know more about this issue. Link to comment Share on other sites More sharing options...
scott levine Posted January 4, 2007 Share Posted January 4, 2007 I would call Rita in service at Mamiya, 914-347-3300. You should be able to have the mounts replaced. I don't know the cost, but I can tell you it will be done right. Mamiya's service department is second to none! Link to comment Share on other sites More sharing options...

bueh Posted January 4, 2007 Author Share Posted January 4, 2007 Scott, I'm in Germany. I had to deal with Mamiya Deutschland once to have my RZ maintainced and their prices were simply outragous. Sheldon, if there is an easy fix for this problem why go through the hassle of packaging, shipping, waiting for the refund and dealing with slow bureaucracy?

scott levine Posted January 4, 2007 Share Posted January 4, 2007 Less than one mm should not create an issue with exposure. If you have the 35mm or 45mm lens, they tend to have a stiff barrel which causes this kind of wear. Link to comment Share on other sites More sharing options...
