| | Comments (2) | TrackBacks (1)

The following is a news release from Canon, Inc about serious problems affecting image storage with the EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D, EOS Digital Rebel XT / EOS 350D Digital / EOS Kiss Digital N series of digital SLR cameras:

May 20, 2005
Canon U.S.A.

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
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.
We are now making arrangements to release new camera firmware incorporating the correction of this problem by the end of May 2005. In the meantime, please be aware of the following when using these models.

  • Before pressing the [DISPLAY] button to check captured images, make sure the access lamp is off, indicating that files have been written to the media.
  • When this problem occurs, remove and re-install the battery to restore correct operation.

2. Disappearance of images when using Lexar Compact Flash Cards
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
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.
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.

Lexar customers can contact Lexar Professional Support in US at (+1) 510-413-1233, or in UK at (+44) 1483-522-947 or visit Lexar on-line at
