As I was shooting down near Lake Burley Griffin I was surprised to see this balloon almost on top of me. I later discovered that it was so close because it had been launched from a nearby park. Although I'd packed away most of my kit by then, I grabbed the 40D and took a bunch of (hand-held) shots of it as it went up... of which I'd judge this to be the most photogenic. It also restores my faith in the 24-105's IS capabilities.
