There are three lenses for the System 600 that I'm curious about: the Curtagon 60/3.5, Xenotar 80/2.8 and Apo-symmar 90/4. The latter is still available and there are several reviews and opinions on the web. However the first two don't seem to be mentioned much, perhaps they were discontinued before web based reviews and info were commonplace. I'm considering adding to my SLR setup, and am trying out various scenarios, either replacing or augmenting the 80/2 with one (or two) of the above. I can't recall ever seeing the Xenotar 80/2.8 or Curtagon 60/3.5 for sale anywhere, and have no idea how many are out there or what their owners are doing (probably just shooting film and enjoying themselves, I would guess). The 90/4 does show up now and again. Any idea as to where I can both learn more about these lenses as well as perhaps find one or more for sale? Any suggestions as to replacing the 80/2 with one or two of these other lenses (losing a bit of speed but at the same time either gaining macro capabilities or perhaps cutting down substantially on weight)?
