Hi guys,
I just recently purchased a slightly used Canon 5D2 and I was testing it today and for some reason I am having a very hard time understanding the auto foucs button. Now on my xsi, there is a similar button to set focus points which I also see on the 5D2 as well but whenever I press the button to change foucs points it will not allow me to do anything. I have been reading the manual and it is saying to press auto focus button and select which should be very simple but either I am doing something wrong or could be somethig else. I am praying it has something to do with setting. I am a little worried and anxious to find the right answer. I cleared all previous settings from main menu and still no luck. Also, whenever I press the shutter button half way to set the foucs points nothing happens.
Karim.
