Mike, Kenny, Sindri, Mitch, Erik, Cooper911.....Thanks so much for the nice remarks. They are always very much appreciated.
Mitch....They are fast flyers, but we have enough of them around to where eventually get lucky. The percent of keepers shots is very, very tiny.
Kenny....Your absolutely right....they are not as fast as swallows......maybe that's the reason I can't get any good shots of swallows in flight.
Erik....I sure like the 500, but it is a hog of a lens for an old guy like me to swing around. I love to shoot with it off a tripod, but it seems that most of my shots end up being freehand shots, and when I finish shooting......I feel like I just got done working out at the gym.
