I suppose this has been asked and answered a hundred times, so I suppose this will be #101. I've been using a Canon 40D for 5 yrs, with good lenses, and have taken some winning shots, with detail, color about as good as one could see. Not to brag here, but to ask opinions of just what benefits you have seen with a full frame. Don't know if I really need one, but I kinda hate to live my life never having used one. Thanks
