What do you think?
So… based on the note, it looks to me like they've isolated the serial numbers, so they don't think it impacts all Canon EOS 5D Mark IIIs
But, they don't say what they're really going to be doing to fix anyone's camera – what does the word “inspect” mean in this case? They say it is minor and I sure agree (many blogs are blowing this way out of proportion!).
Is this a good enough solution?
