..if I could do more than 1/160 I'll be more than happy, but that would mean getting a HSS flash?
You can sync without HSS at up to 1/180 .... Your camera is set to 1/3 stops. If you go into your menu and switch to 1/2 stops, you will get 1/180.
FYI- High Shutter Speed (HSS) flash is sort of misleading. It is actually the flash strobed rapidly as the shutter slit passes over the sensor, so the flash only puts out a fraction of its power with each strobe. It still takes 1/180 for the moving slit to cross over the entire sensor. It however might be a difference that makes no difference when doing bug macros. The subject isn't moving during the 1/180, and at macro range, you usually have to reduce the power of the flash anyhow.
