Have a Leica kit myself .....and test results vs Canon EOS GEAR ......it's in a different ballpark, state, country, resolution for me at least is simply superb, lens quality simply brilliant. Love the old school feel that I used to have with my old Canon EOS film cameras.
Just my 2 cents...sadly I cannot afford any mores lenses but I don't care....I am big enough to go without. :-)
