Help with Sigma Flash

Hi all,
I just recievd my new Kr from Digital Camera Warehouse which they offered with the Sigma ef-530dg ST flash.
Problem is when I put it on the images are all majorly over exposed. The iso is set to auto and it's taking the shot at 1600iso. Everyting else is set to auto so I thought P-ttl should work??
Anyone got some advice please!!
Fritz.

Don't shoot in auto; use other camera mode (Av, M,..) and set the iso to 100/200; set the flash to P-TTL and you should be OK.

Set the camera to P mode (it's AUTO anyway), it shouldn't change the ISO value; I don't know for sure because I always shoot in Av or M mode and I don't have the camera with me to test it, but I may check it later on. You could try it and see what it does.

Even with the ISO set to 1600 you shouldn't get overexposed photos; are you setting the flash to P-TTL?
