I'll admit to using this camera a lot in the last three months. I shot about 10 rolls of film thru it. I went to open it the other day and it only opens to about 45 degrees and then stops. I don't want to force it open. The day previous I had a problem with the shutter trigger not working so upon inspection it seems that the trigger mechanism has worked loose from the shutter release. So to shoot the camera,I would just push the shutter release. I do the same thing with my Zeiss Ikonta 521/16. I am going to use a strong light to look in and around the camera to see if something is binding or has worked loose for a start. Just wondering if anyone has experienced the same problem? Thanks for any help.
