A friend looked at my camera and said that he had a problem with the 28-300mm lens. He said it was too small (compared to his nikon) and that it had an unusual 28-300configuration. I am an amateur and don't know about such things. He is a Nikon owner, knows his stuff and takes really nice pictures. Is he right or is this a phony 1:2.8-4.9 zoom lens;Something along the lines of the $50 point and shoot cameras that claim to have high quality german lenses. Thanks in advance.
