Good point!
Like I said, I have no experience shooting with a flash at all, just learning the basics. But this makes sense - so if I set a relatively low ISO and just fire a flash it will freeze the action even at the longer shutter speed? This flash is rated down to 1/20000s apparently, but I could not find a way to vary the flash time so far, only power output. Manual sucks.
BTW, I will be shooting with a Tamron 70-20 f/2.8, so I might be able to get some good shots at higher ISO without the flash - just wanted to see if I can minimize the noise with the flash instead. And I didn't want to spend $400 on a Pentax flash, being flash novice - hence the el-cheapo chinese flash. Although I must say, it does produce impressive results, from my limited testing so far - I don't regret buying it, even if I cant use it for my intended purpose
