To the younger ones, the Paris metro must look like a gigantic labyrinth. A great place to play and run around, but making sure to never cut the parental Ariadne's thread. (click on picture for high res)

Leica M9 with 50mm Summicron at F2.0, 1/125, ISO160
Great composition and subject but bokeh do it all, IMHO!!!
Yes, the bokeh of the 50mm Cron is great (though any lens would have rendered similarly in this specific shot). One of the instances were foreground bokeh is stronger then background ;)
great composition! I have a question, do you personally prefer 50 Lux or 50 Cron? Why?
I have owned both. I prefer the Cron for how it draws portraits at F2.0 and has a more classic look. The lux is a perfect lens with very smooth bokeh, but the look was a bit too modern to my taste and I already own the 60mm Hexanon Konica for large aperture shooting. Cheers.
Thanks :) your taste is superb!
cheers,

btw, which version of 50 summicron do you use?
