Simon, I have a Tamron 180 Macron too. Great macro lens.
I have took a number of dragonflies, but I have never managed to resolve the compound eyes as in your Pic 6. The resolution of Pic 6 can see boundaries of each compound eye.
errrrrr.... I supposed if you can capture enough details with accurate focusing then you should be able to see the details when you zoom into the picture... (I think ;P) mabe the season insect photographer can tell u more, I'm just a newbie :bsmilie:
here is another shot taken with my trusty 70-300mm sigma
resized original shot
cropped to 640x480 without resizing
1/200, ISO 400, f16 at 260mm..
