Canon says firmware fixes 7D ghost images

An update to Canon's EOS 7D SLR takes care of a problem where traces of one image could show in the next.

Canon has released new firmware for its EOS 7D camera that it says fixes a ghost-image problem in which faint traces of one image could show in the next.

Version 1.1.0 of the camera firmware "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," Canon said of the update.

The ghost-image problem showed only in some circumstances when the camera was used in continuous-shooting mode and was more apparent when software was used to enhance the image.

The Canon 7D , which just arrived on the market, costs about $1,700 and can shoot 18-megapixel images at speeds of up to eight frames per second.
