Left: 24-70 at 70mm, right 70-200 at 70mm, both at f/5.6


Above, 100% crops from the 6MP image
Both with 70-200 at 200mm, at 1.55m distance. 

More technical details -- all images shot in RAW format
with EOS 10D 6MP camera, tripod mounted, mirror lockup,
at ISO 100, indoors with mostly natural light. Minimal
unsharp mask applied and no saturated added to the 100% crops.
Unsharp mask used was Amount 100%, Radius 1.0, Threshold 2
using PS CS2 (PS ver. 9). I realize at f/2.8 I could have strived
to better focus on the exact same point of the flower when I swapped lenses.
