OK. So, am coming from a medium format background and have made a BIG jump to digital by buying a D800. Talk about jumping in the deep end. So I'm learning day by day all about this extraordinary tool and have been having a lot of trouble getting the inbuilt flash to operate consistently. We are going away camping tomorrow and repair will have to wait until I get back. Can get by without flash doing landscape. One last analysis I thought. Go to Live View- flash charge icon up, put it up to my eye- flash charge icon out. Go to Live View -flash fires, use eyefinder- no flash. GRRR! Move away from my eye slightly- flash fires. ###? Eureka!
I wear a peaked cap most times and the tip of the peak was touching the popup flash just enough to deactivate it. Hmmm. Very hi-tech- NOT! Happy New Year all.
