Canon has released a firmware update for the EOS 7D.  The new version 1.1.0 is supposed to address the strange ghosting issue that was uncovered last week.

Canon’s official word about the firmware:

1. Corrects a phenomenon that in images captured by continuous shooting, and under certain conditions, barely noticeable traces of the immediately preceding frame may be visible.
