I found this one in my neighborhood, an amazing discovery:
this lens is now a kind of collector's item.
The 200mm 5.6 is a very special concept: included modelling lamps and ring flash, with everything mechanical on the lens: select ISO, magnification factor (in combination with close up lenses), and aperture (fixed depending on the other choices, flash intensity being constant). There is no focus ring, focus is achieved by moving back and forth (a technique I am already using with classical macro lenses).
