The second and third versions have the same optical formula of six elements in four groups. The fourth version (Mandler) has seven elements in five groups. The fourth version (79-97) is the one that is known as the "king of boke". However there is a lot of confusion over just what it is famous for. It is only in the middle apertures that it is creamy smooth in the transition from in focus to out of focus. Wide open it has some pretty vicious spherical aberrations. There were some reports of loose front elements in the fourth version. I never had any trouble with mine. John Collier On 8-Feb-07, at 3:20 PM, Frank Filippone wrote: > Version 3......
