Just a few months back I bought the Kenko extension tubes from Amazon to be able to make macro photos. The reason I went with the Kenko is that they connect the electronics of your lens to the camera so that auto-focus etc will work. You can absolutely go with a cheaper option and still get the same great photos. or you can buy the Canon at tripple the price :)
During our summer vacation I did not get a lot of macro work done but at least I got a Dragonfly mounted on top of a flower just next to the pool. The insect was sometimes flying about but returned to his starting position giving me time to get my gear and land a pretty decent photo. I was lacking my tripod and that is a pity because getting a sharp image can be quite hard due to the zoom that is needed.
This particular photo was taken with two tubes mounted, I believe it was the 36mm and 12mm, and the lens was the EF-S 18-200mm extended to maximum zoom to prevent the dragonfly to leave. Going closer meant it would leave, and I tried a few times to be honest.
I am sure I will do more macro work in the future :) Quite good fun!
