We have received inquiries about the problem of images disappearing when using specific digital SLR cameras. As a result of our investigation, we found that the following two problems may occur. Please be advised of the details and countermeasures.
 

1. Disappearance of images within the camera's buffer memory

Affected Products:

EOS —1Ds Mark II, EOS—1D Mark II
 

Problem:

Pressing the [DISPLAY] button immediately after shooting with the camera set to "RAW+JPEG (high image quality)" causes the LCD monitor to become entirely white and the camera to lock up, losing all the images in the buffer. This problem is caused by the firmware for these models and sometimes occurs regardless of the recording media used.

Countermeasure:

The firmware to correct this problem is now available for download on the Consumer Site. Click here to download the firmware.

Affected Products (D-SLR):

EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D, EOS Digital Rebel XT / EOS 350D Digital / EOS Kiss Digital N

Affected Products (CF card):

Lexar Professional 80x-speed Compact Flash cards

Problem:

Captured images on some Lexar CompactFlash cards can be lost when used with the Canon cameras listed above. Working together, Lexar and Canon have investigated the cause and confirmed that the problem occurs in extremely rare instances when the products above are used together.

Countermeasure:

Lexar will offer a free firmware update incorporating the correction of this problem by the end of May 2005 for Lexar Professional Series 80x CompactFlash card customers using the affected Canon cameras.
