I'm using Back Button Focus on my D-5100 but find the following annoying and wonder if I have my setting set correctly. At times, if I try to re-focus nothing will happen unless I depress the shutter button half-way down. It seems the camera has to go thru some sort of metering or something before it will allow the back button to re-focus. I have my auto focus mode set to AF-C and my AF area mode to single point.
Should this be happening?
