Yes.The shutter is basically firing as supposed at all times. All brass connectors: body pins, back pins left zero dirt residue while cleaned with rubbing alcohol. Same with battery slot connectors. I’m thinking it’s some kind of bad solder inside body ( I hear delicate rattle). Yea I got half lucky I don’t really shoot in automatic modes aside from my digital, I like to stop and think while working with film cameras. I hope technician will fix it.
