You may agree with sveamarcus, but personally I think there is a world of difference between 'testing' a lens and actually using a lens. I wouldn't dream of recommending, or criticising, something I hadn't used over a period of time. 'Testing' in my book is contrived comment, it doesn't relate to the world outside the camera shop window in most cases. He may have used a lab, or a sharp brick wall, but I'd take seriously the person that had lugged it up a mountain and had a genuine feeling for if it was worth the effort.
