I have a Leica CL on the way... I'm most likely going to get a 40 'Cron/Rokkor, but I am also considering a 50mm f2 lens. How good/not good is this camera for focusing a 50 f2 lens? Is your hit-rate decent? I can focus on my M3 at 50/1.5-50/2.0 fine, but with some cameras, like my Contax T, focusing wide open is chancier.
