D600 and Sigma flash
I bought one of the D600's at the fire sale price and then found a Sigma EF-610DG Super for a good deal also. They work great together when its on the shoe, but when I tried to use it in CMD mode I can get the flash to fire, but its not firing with the camera. Its really firing hard and putting out a ton of light, so its not just sensing output or anything. Ideas? I am new to Nikon so it could be something simple I am not doing, or will this flash even work with the D600?
