Setting high ISO
I am having trouble enabling the high ISO (3200) setting using the Custom Function on my new EOS 40D. I have gone through the process of choosing "On" under CF1 number 3, but I cannot obtain the setting on the camera. Has anyone else come across this, or can advise whether I am missing something?
I hope this has not already been covered in the forum; I tried searching but received a message saying the facility was not currently available.
Any help would be much appreciated.
