I got to play with the Cooke soft focus lens for a few days. some test images at collum.omniblog.com . A very impressive piece of glass (not to mention expensive). Amazingly sharp at > f11 (in fact, one of the sharpest lenses i've used). A very unique look from f11 to f4.5.
Anyone compare this to the original Pinkham & Smith Visual Quality Series IV that it's modeled after?
