Canon Says It Will Fix Ghosting Problem In EOS 7D

Oct 27, 2009
Though Canon's EOS 7D only hit shelves a few weeks ago, the company is saying there already may be a problem with its new mid-range pro digital SLR. Canon issued a service advisory today to a address a "residual image" issue with the DSLR.

According to the advisory, which can be read below or by clicking here, Canon has confirmed a "phenomenon" in images captured in the 7D's continuous shooting or "burst" mode where "barely noticeable traces of the immediately preceding frame may be visible."

The phenomenon, which is commonly known as "ghosting," is not noticeable in images shot with "optimal exposure" with the 7D.

Canon said it's currently investigating the problem and will release a firmware update for the camera to fix the issue.
