->> I have a brand new D300s and was shooting tonight with a new SB900 flash on camera bouncing. After shooting for maybe 50 frames the camera turned off and would not turn back on. Plus, my 28-70 motor seems fried and will not auto-focus on any Nikon camera I put it on. It actually felt hot to the touch. Has anyone had this experience or can offer any advice? I tried putting in new batteries and the camera will not turn on.
