Where else can you get this level of photographic entertainment for free? There's a recent thread where a guy is comparing the image quality of the Pan 100-300mm to the Olympus 75-300mm II. Both pictures are horrendous and you suspect right away his "test" not only is unscientific but probably bone-headed as well. Sure enough, he finally admits he was shooting the scene through a window and hilarity ensues. I can't decide if the responses or his ultimate indignation at the criticism is funnier. Check it out.
