Thanks to Sean for finding this link. I thought it was really interesting on a number of levels. But great discussion of light, working what you have, and knowing your camera.

Which got me thinking, how long does it take to really know your camera? I got to the point with the 7D that I really felt I knew it. But, I have to admit, with the 5DIII, I am still not quit there. I think part of this is that I changed up my lenses at the midpoint of owning it (24-105 to 24-70 II and 100-400L to 70-200 II/150-600S) whereas with the 7D I had the EFS 15-85 and 100-400L the entire time.

But the thought makes me want to head out and just shoot my lens/body combinations a bunch more.
