Hey guys, I’m new lol I have recently upgraded from a old canon to a eos r. I bought one used last week and I love it. After about 30 shots , I am getting a error code 30. I have the opportunity to return it. From what I have found, it’s a shutter malfunction I think. When I called the place they said it could be anything and said it might just need a new battery. Should I have them send a battery or a different camera? I just don’t know enough about shutters. Any advice would be great. Shawn
