I found both online at about the same price. Any opinion on which on to get? I read some comparison that leica is sharper and has more contrast but Nokton is f1.4. My roommate's dad is visiting and he brought 2 leica bodies and 3 lenses. I try the leica lenses and they are beyond my imagination. Very sharp. Beautiful color and nice contrast. The photos I got need no post processing. JPEG out of E-P1 is too beautiful to retouch. So I'm looking for a leica lens of mine. Summicron-c and Nokton are in my affordable range and it's good to start with them before I dig deeper into Leica's world. Any thought?
