I was playing with my friend 5dmk3 and it is amazing. I am looking to get it soon. I am confused regarding the AE-hold mode. I was able to lock the exposure using the spot metering mode and see "*" in the viewfinder. When I moved the focus point to another one, the "*"/AE-hold seems to disappear. Can someone point out the error for me or explain to me proper way to use the AE-hold?
thanks
