Canon has warned that traces of one photograph taken with the company's new higher-end EOS 7D SLR can sometimes be seen in the next.
The good news: new software for the camera should be able to fix the problem at some point. "Canon is currently investigating and analyzing the cause of this phenomenon, and we are planning to release a firmware update to address this issue," the company said in a a service notice.
The problem occurs only when shooting continuously, Canon said: "In images captured by continuous shooting, and under certain conditions, barely noticeable traces of the immediately preceding frame may be visible. 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."
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.
