Canon have released a new firmware update (version 1.1.2) for the EOS-1Ds Mark II DSLR.

This firmware update (version 1.1.2) includes the following additional functons and improvements:

1. When pressing the DISPLAY button immediately after shooting, the LCD monitor would turn completely white, the camera would hang, and the images in the buffer memory would be lost. Countermeasures for this issue have been incorporated into this update.
2. Errata in the German and Russian language displays have been corrected.

This firmware update applies to cameras with firmware version up to 1.1.1 installed. If your camera’s firmware is already version 1.1.2, it is not necessary to perform this update.
