To the lens experts out there...A couple of famous soft focus lenses work on this principal, for instance the Cooke soft focus lens which is again being made (but very expensive). These were orginally made by Taylor Taylor and Hobson. My memory is that this lens works by moving the center element.
Triplets are very sensitive to element spacing but there are sucessful front element focusing Triplets so that may not work for getting a good soft focus effect. Some experimenting can be done by shimming the various elements to vary them. Unscrewing the front cell will move both front and center elememts together in most, if not all, Triplets, nonetheless, its very simple to do and won't hurt the lens.
