Just two...
Although not the top shelf from a technical perspective, the subject matter and low to the ground shooting brought back these rewards. I was lying on a blanket at the shoreline and used a Kirk Fat Bean Bag with the Sigma 500/4.5. First two images were taken with that other system...
Dancing with Dragons Greater Yellowlegs - foraging for food:
(note OOF blue dragonfly above it's head)
I managed to last 30 minutes before the heat of the sun and the crawling insects was convincing me it was time to pack it in.
This next image was taken in a blind - again in that very hot temps down by the Rio Grande Valley. It was around 108F (heat indexed) outside the blind. Used the K20D + FA* 300/2.8 + Tamron 1.4x TC... cropped the top some to give better balance to the image.
Roseate Spoonbill
Now a crop of the Spoonbill image.
It seems to hold up nicely, with over 2600 pixels left on the long side...
