why not u try it? i had try all the combination, also can't make it.
if you said 1/5000s too fast, but i use 1/1000s, 1/250, 1/125, 1/60, 1/30...etc
if too slow, can't make the fan still, if too fast, fan become bend, there is no middle point...
sorry i dont hv the phone, im jus helping based on my experience
fyi flashlight normally have effective bust time frame in between 1/200s to 1/500s (lower if using led flash)
this prob happen if da camera finish taking the pix before the flash burst
since the flashlight hv limitation... u need to hv external light source... a strong one
i know it coz there is hacking kits for canon camera, called CHDK
they hack the camera feature to the maximum

tat y i said... 1/5000s is possible... if cant do it, sensor prob lor
anyway im off now, gud luck on the experiment
