Canon 50D firmware fixes Error 99
The dread error 99 can appear on Canon DSLR bodies for any number of reasons and when it does, you’re out of business until you fix the problem (clean lens contacts, charge battery, etc.).
My guess is that on newer bodies there are an increasing number of backward compatibility issues with older lenses. Those can be fixed with a firmware update.
