I have a 60D and I was using the kit 18-200mm lens and I saw a bunch of photographers set up at spot to get a picture of Seattle. There were 3 different people with 600mm L lenses ($7000). I went up to one of them and just asked if they were there to take pictures of the moon an he said "no" and then just turned around and looked at the view.
Do you have tricks to peaking a professional photographers interest when you are carrying amature gear?
