I bought this one on ebay and just got it. Outside of what looks like a few air bubbles inside the lens, its in good shape. I just wanted a 1.5 because i do have a collapsible f2 that is numbers matching to the contax ii, but its got quite a bit of cleaning marks on it. Not bad, but not perfect.

I should be getting my contax ii back from oleg soon.

That was a really good price- lens looks good. I have a coated and an uncoated Sonnar from this same batch. Note the unmarked F16 setting, my two are the same as this.
