By sheer coincidence, the same day I got the postal notice of my SMCP K 50/1.2 arrival, I saw on Adorama the SMCP A 50/1.2. And indeed it is really the lens I was after. Eventually I had a very similar postal notice in my mailbox.
Again, being very predictable I've taken my newest aquisition to my office. Here is a portrait of my co-worker shot at blank-point range at f/1.8.
