I just called Nikon USA for a simple Auto FP (high Speed Sync) question about the on camera flash and SB-400... no one at nikon seems to know anything about their own camera and flash... I understand that the support staff needs to know a lot nikon cameras... HOWEVER I feel that is NOT a excuse for not knowing your pro cameras FP mode....
Canon Professional service... Please produce a High Mega Pix Camera and I come back to you!!!
Man I miss Canon Support!!!
