Your lens did very well in your hands. I am looking for such a 75/1.4 lens. The asking prices vary greatly online.

I bought this lens in a flea market for $400. The glass was not scratched, but it had severe hazing. It has an Exakta mount. The seller knew the lens was worth something but he was not really sure, I talked him down from $700.

I sent it to Youxin Ye, and it came back very smooth, with spotless glass. But it was still severely back focussing.

One more trip to Youxin and the lens was just about perfect. I shoot it on my Sony A7 with an adapter. It is an early 1950's Zeiss Jena lens, with the high quality "Q" export markings. I'm pretty sure single coating.

Total cost to me about $600 and lens is in excellent condition with excellent++ glass.
