I get that all the time at my daughter's soccer games. Everyone makes comments that if they had an expensive camera like mine, then they could get the great shots. Never mind the five years I've been shooting sports, the hundreds of rolls of film I've shot, the countless hours spent reading about photography (and the hundreds of dollars spent on books and magazines). It's tempting to one day hand one of them my camera and say "Have at it." I could burn them a CD and they could see for themselves.
On the other hand, why bother...
Let them think it's the camera.
