Before I install this firmware update I thought that I had better ask for a little help.
If I am reading the Canon web site correctly the FIR file should be 33.02 MB once expanded. However, when I download the file, expand and then right click to properties I show the downloaded file to be 32,988,060 bytes. I have downloaded and expanded the file two times and get the same 32,988,060 bytes on both downloads but the apparent difference caused a little concern.
When in doubt ask for help. Do I have the full file for updating? Want to be sure before attempting to install on the camera.
