You are the person whose questions I was answering last night. I just happened to see this post too. I'm not shadowing you intentionally. Please let me fill you in on the hard facts about used Hasselblads. When you buy one without knowing it's history, it should be shipped directly to a service person, truth be known. Even if it works well, there is a very high likelihood that the focus will be off to an unacceptable degree. And with a C, you have 2 places where a problem may lie. Somebody may have tinkered with the screen alignment for one thing. On a CM/ELM this is less likely. But even with the screen being ok, there are 3 little foam pads between the backside of the mirror and it's metal backing plate that are almost certainly deteriorated this goes for all c and El series. BTW, please specify to your repairer that you want these pads replaced on the one you just sent out. When these foam pads are deteriorated, focus accuracy is compromised to a serious degree. I remember working on one that was so bad, it was no better than a box camera in focus quality. If you want to find the best thing for your money without necessarily having to service it right away find a 553 ELX in good shape. GL.
