I've seen that while the Q will synch flashes at 1/2000s this only applies for the internal flash and for certain lenses (is it only the 01 and 02). For the Q it's stated that external flashes will only synch down to 1/250s.
The Q10 is a slightly different beast so I put this to the test. With the 02 zoom and some Yongnuo flash triggers, I can confirm that I could synch EXTERNAL flash down to 1/2000s
Yes, I'm happy, that gives three extra stops of light against the ambient.
I haven't tried external flash with an adapted lens yet - I'll report back when I have.
