Canon EOS 7D May Show Traces of Previous Image when Shooting in Continuous Mode
October 27, 2009 -- Canon today published a service advisory for the EOS 7D where they have discovered an issue where slight traces of the immediately preceding frame may be visible in subsequent frames when using continuous shooting mode. This phenomenon is not noticeable in an image with optimal exposure. The phenomenon may become more noticeable if a retouching process such as level compensation is applied to emphasize the image.
Canon says that they are investigating and analyzing the cause of this problem and will release a firmware update in the near future to address this issue.
Once the support measures have been established, Canon will post the relevant
information to their web site.
