As much as I like this shot, it could've been so much better. It was shot with my 100-400 L with a kenko 1.4x teleconverter. I was out photographing birds, and these two passed by. It was too good to pass up, but I had no time to get rid of the TC or get out of my dusty truck. Not only did I loose some sharpness with the TC, but I also took the photo through my dirty windshield! Oh well, I hope you like the photo.
