I had this problem about a year ago. Intermittently the 50mm lens would sound like it fired, but did not. The Samys' Hasselblad repairman instead of doing the CLA himself sent it off for a full overhaul. It seems that my lens had heavy use and wear from the previous owner and Hasselblad rebuilt my lens. I hope that yours does not need the work mine does, but I recommend that rather than lose more photographs you should have the lens checked out and serviced.
Thanks for that info. I do anticipate having to get it serviced, but I was curious why the lens would work on one 500C/M and not another.
Tolerances and wear variations.
If the lens was always used on one body, the two can have changes match each other nicely over time. But put the lens on an other body and the wear on the lens is out of tolerance for the second body.
I didn't say anything in my first post, but I too suspect this is what is happening. Do you think this is something that can be fixed to work on my 500C/M?
In the meantime, you might try putting the pressure on the lens when mounted to your camera and see if that corrects the problem. Let's say the flange is worn. Is there a little slop when mounted, allowing the lens to rotate a bit? Apply some rotational pressure and fire the shutter, see if it works. Maybe there is some front/back slop? Again, maybe pressing the lens lightly to one end or the other of its slop will get it to work.

Something about a shaft that was worn out.

Thank you all. I think I’m just going to decline to buy it, considering the likelihood that this is a wear issue, and not likely to be resolved without considerable expense.
