This lens makes it so easy to shoot flowers. It already focuses as close as .34 ft, thus making it a macro lens as well. But if you add a extension tube of as little as 12mm, a whole new world opens up. I have the whole set of Kenko ET's (12mm, 20mm and 36mm).
Anyhow, the latest examples of the power of the 24-70L.
And then something not flower related.
