It being my birthday last week, I bought myself a NICE birthday present that I had to go out and play with this morning -- a Canon 400mm DO f/4 IS lens. It was mucho expensive... but I did save $1,725 by buying it used on eBay!
The pix I took ad uploaded today were shot on a 7D with the 400mm DO and a 1.4X TC hand-held. Most of the shots I posted were severe crops, though this one reflects about 1/4 of the frame. I'm very happy with the results.
