Hmmm... That's interesting to me, if true. I do have both a VS1 600/8 Solid Cat and a Perkin-Elmer 600/8 Solid Cat (identical except for the coatings, as far as I can tell). I was never aware of any other versions of the design - I am curious (but a little dubious) about whether that "Leica R 600mm mirror lens" could be another incarnation of the original Perkin-Elmer design or not... > I'll tell you, that was one heavy lens! Indeed! By the way, my impression of the VS1 600/8's "big brother" (well, it's actually almost the same size), the VS1 800/11, is that it is not as good a lens as is the 600/8. Has anyone else ever tried the 800/11? Fred
