Thanks Gary. Exploiting these old lenses' imperfections is actually a nice occupation (a bit expensive too - but no, I'm not gonna buy a Noct). I am starting to understand what other Members here call a "boring" lens. For instance the very good Voigtländer 40/2 could easily become one of these; it requires many more efforts to get an "aha" shot with it. On the other hand, the 50/1.4 SC has more use cases than a Lomograph, as the opposing shots above demonstrate. I still wonder why Lightroom refused to correct the LoCA (the one aberration I never found usable, it simply puts me off). BW conversion should not become the only answer.
