After the rather stange disappearance yesterday of the new firmware update for the Canon EOS 20D DSLR, Canon USA have issued the following statement to try and explain exactly what is going on.

Canon Inc. has acknowledged the EOS 20D lock-up issue as follows:

Canon is aware of this [EOS 20D lock-up] issue; it is currently being investigated. It seems to occur very rarely, under extremely limited conditions. If it does occur, you can remove and reinsert the battery to restore your camera to its normal condition. Please note that this issue does not affect images taken with the camera. We plan to release a firmware update for download from the Web when the appropriate countermeasures are determined; we will let you know the schedule for this release when it becomes available.”

So I guess all you 20D owners will have to sit tight and wait for a new version of firmware to appear that will fix this issue once and for all.
