As I said, this is my primary lense, and I have thousands of images shot at ~3' and the DOF on ones I looked at tonight show at least 1" or more, and the subject matter has detail enough (clothing texture) to easily show this detail. I'll have to go find a tulip...but that'll have to wait a few months...since we just got 2' of snow...
