Canon releases new firmware for Mark II cameras  
Monday, May 30, 2005 | by Rob Galbraith

Canon today has released firmware for the EOS-1D Mark II and EOS-1Ds Mark II that is meant to eliminate a camera lock-up problem the company acknowledged earlier this month.

Errors in the Russian and German language menus have also been corrected in the new firmware release.

Firmware v1.2.2 for the EOS-1D Mark II is available here. Firmware v1.1.2 for the EOS-1Ds Mark II is available here. A valid camera serial number is required to access the downloads.

Lexar also developing firmware update

Canon's May 19, 2005 statement coincided with a separate one from Lexar, in which the flash memory maker revealed that it was developing updated card firmware for certain 80X-series CompactFlash cards. The new firmware is designed to fix an image corruption problem that apparently can occur under rare circumstances with five different models of Canon digital SLR.

Information on which 80X cards are affected and how the firmware update would be rolled out is to be released by the end of May 2005, said Lexar in its statement, though as of this writing we don't have any officially-supplied information beyond what was in our earlier story, and Lexar hasn't yet updated its web site advisory.

From a conversation with a Lexar tech support representative late last week, however, it would appear that 80X CompactFlash cards whose edge stamp ends in A4B6 will require a firmware update to solve an image corruption problem with these cameras:

  • EOS-1Ds Mark II
  • EOS-1D Mark II
  • EOS 20D
  • EOS 20Da
  • EOS Digital Rebel XT/350D

    More-recent 80X cards, ones whose edge stamp ends in 9171, may not experience image corruption in the Mark II cameras, but will require a firmware update to fix a potential image corruption problem when used in the EOS 20D/20Da and EOS Digital Rebel XT/350D. At this point, we're assuming that earlier 80X CompactFlash cards with an edge stamp ending in something other than A4B6 or 9171 are free of this Canon camera incompatibility.
