When I shoot with my Triopo speedlight I have to set my camera to f/5.6 and 1/100 with the flash at 1/4 power. 

If I increase the flash power, the picture is black. If I change the shutter speed or aperture, the picture blurs. 

I want a simple way to adjust both the flash and camera to any shooting mode I need .
Note that I am using a 55-200 lens.
