Slapped the lens on today and took a few quick snaps. I have to say that I've been spoiled by AF and this thing has a looooong throw. Of course that make MF all the better, but with my shooting style it is a challenge. The thing is brutally sharp though - imho outperforming my 43/1.9 in that regard (shooting at about 2.8). Just due to the fact that I often do a lot of "hip shooting", this one will likely see more limited use, but it appears to be a keeper. For times when I have both hands free it'll rock.
A few snaps, nothing earth shattering, just messing around to get a feel for the look.
