I thought I remember reading somewhere that you can set the D70/D70s to trigger(take a photo) based on a set focus. I know about using Focus Lock using AE-L/AF-L button to set focus but you still have to press the shutter button. Isn't there a way to set the focus and have camera firing off a pic when something comes into focus? I have looked all over in the manual and also searched the web for such info but I did not find the information I read. It was some time ago so maybe I am just mistaken.
