<p>I have not used my AX for over 1 year. It now seems to lock occasionally. When it locks, if I move the mode lever to Macro, then lightly press the shutter button, it frees it. I can then switch back to Manual/Single AF/or Cont. AF. and everything is perfect again in the viewfinder. The battery is OK, having tested it in another make of camera. I have been in touch with a man who worked as a camera technician with Contax here in the UK. He believes that non-use of the camera had caused this malfunction. He suggests moving the mode switch back and forth; and firing the shutter frequently, should bring the camera out of its "slumber". Everything works fine in Macro mode with no 'lock-up' It only locks occasionally when it SAF/or CAF. when using 'program'/TV/AV. When switching to Macro, and back to the other modes I can hear the film plane moving smoothly and correctly.<br> There is nothing to suggest that it is 'mirror slip' causing this problem.<br> Any suggestions and comments from AX users would be appreciated.<br> Thanks.</p>
