I have a 580EX flash unit which is quite good. I decided to mess with the multi-flash feature this morning just to see how it works. The conditions were far from ideal, but I did get several shots like this one - a bouncing golf ball. Now I want to make sure that everybody understands that I DO NOT PLAY GOLF. There are many out there who play golf and spend hours watching golf on TV. I am not one of them. I tried to play several times because that was the entertainment at our Division meetings. It wasn't much fun for me because I couldn't even hit the dang ball. What I did learn is that you can store a lot of beer on a golf cart. I also learned that you can only drink so much beer before you have to hit a ball out into the trees so that you can get some relief.
