And with more then 24mm, you have to be danger close to your subject to get a focussed shot.
As for the lens itself, the problem I had with it is the focus distance. The bee shot i've posted is the closest I could get before going OOF. So I think I will get clearer shots with the 24 70 and extension tube, but will be short on the focal range. I'm gonna have to trial and error on this.
The TC is the next thing on my shopping list. I just need to get a nice deal on the version III of Nikon's TC. I've seen a comparo of the two lasts versions and the II version is not even worth looking at compared to the version III.

I use Canon ETs with my Canon lenses and the all "Report" EXIF. When the effective aperture gets smaller than f/5.6, then AF will slow dramatically or stop. I suspect the same is true with Nikon prosumer bodies.
With shallow DOF you want to get the eye in focus and you do this by physically moving the camera in and out. Take lots of shots and try to get either head-on or side views, where the shallow DOF is less of a worry. It's interesting to observe that if you get the eye in focus and show lots of details around the eyes, no one worries about all the OOF stuff.
