Canon EOS-7D Problem

Canon just issued a service notice for the new EOS-7D. It says that under “certain conditions” (unspecified) in continuous shooting mode slight traces of the previous image may appear on a subsequent image. They apologised profusely and promised a firmware update to fix the problem.

Here is a link to the service notice (USA).

Camera firmware is getting so complex now that this kind of bug will appear more often from all manufacturers. I think software QC still trails hardware by miles.

Of course, as a Frugal Photographer I am delighted at the news. Another reason why I can tell myself I shouldn’t buy this camera that I crave!

    Canon has released a firmware update – version 1.1.0 – that Canon says fixes the problem. See

    Interesting that Canon, slightly defensively, describes the problem as “barely noticeable traces of the immediately preceding frame”. You can almost hear the firmware engineer grumbling about the fix not being worth the trouble.
