May 21, 2005: Canon and Lexar Media have issued joint alerts warning users of some Canon DSLR cameras that captured images may be lost when Lexar Professional 80x-speed CompactFlash are used.
According to the Canon alert, the affected models are the EOS-1Ds Mark II and EOS-1D Mark II. The Lexar alert adds the EOS 20D, EOS 300D and EOS 350D models. Canon has identified the problem as follows: 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.
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 wishing to update their firmware can do so at www.lexar.com/support. Canon is also planning to release new camera firmware correcting the problem by the end of May 2005. In the meantime, the company advises photographers to take the following counter-measures:
– 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.
– If this problem occurs, remove and re-install the battery to restore correct operation.
