Phil, from the quote that you lifted, he doesn't say that 'you can make just as good an image with consumer glass as you can the more expensive stuff', you seem to be reading far more into it. All he is stating is that great pictures do not require expensive equipment. He doesn't say that expensive glass is worthless or overrated at all, in fact he went out of his way to make that clear several times." For some reason, people like to believe that their glass is 'magic' and it's impossible to shoot great portraiture, landscapes, etc without having expensive 'pro' grade optics at one’s side. You want to know the truth, it's all completely B.S."
Your point also seems to be that you can make just as good an image with consumer glass as you can the more expensive stuff. Once again, you are wrong.
