We can only choose from the choices in the poll?
I don't like either of them, mostly because of price but also because of the way they draw.
I prefer the 50mm DR Summicron. Still a lens that can run circles around most glass these days. The fact it doesn't fit on digital Leicas with full compatibility is just a life choice.
So, for wherever, whenever shooting I'd say the DR 'Cron. If I did more shooting in crowded spaces or wanted a wide, I'd choose the 21-35mm Konica.
