Thanks all. I just pulled-up an extensively detailed piece on the Zeiss site. Wow! A good read with more detail than I expected. This guy knows his stuff. Sad, I kinda wanted a good useable camera. I have many others but this one was a real looker to me. The fellow, an engineer I think, wrote each one is pretty much a handmade item. Surely beyond my poor skills, definitely more than my piggy bank can handle. Such is life as I don't own a Red Flag or a Leica either. Patt on the back to those that do .
