Yesterday we posted an internal service advisory for the Canon EOS-1D X and EOS-1D C. These are advisories that are only known to a select few within Canon and not told to the consumers.
We have a lot of more of these documents that cover various Canon lenses and camera bodies, there's even more on the EOS-1D X mirrorbox.
The person that sent them to us didn't have an issue with Canon keeping this stuff internal. However, they were upset that a lot of the issues are known to Canon and they're still charging customers for the repairs out of warranty. There are a couple of lenses with design flaws and Canon is charging $250-$450 for these repairs out of warranty and not fully disclosing the design flaw to the customer.
We're not sure whether or not we'll post the rest of the internal documents we have in our possession. If you think there's value in us doing so, please sound off in our forum.
