But the feeders are located under some evergreen trees in a State park. Had to use the flash and Better Beamer attached. This is at min. focusing distance for the 600, cropped just a 1/2" off left side. We really don't have many hummers around here. If you get 1 in your backyard you are lucky. This park has 5 feeders and draws as many as 75 hummers at one time.....Mike
