David over at Strobist might be able to light circles around me, but one thing we share in common is our passion for the Canon PowerShot G9. David wrote in the article, New Canon Powershot G9 Makes My G7 Feel Like Unloved Stepchild, "I don't write about specific cameras very often on this site, but this one bears a closer look. The G9 is of particular interest because of it's flash-friendly features, among other things."
One of those "flash-friendly features" is that you can sync a Canon G9 up to 1/2500th. This is very handy for high speed flash situations when you want to control motion. You can read all about it in his post, How To: Sync a Canon G9 at 1/2500th of a Sec. It's pretty fun stuff.
