Here is a shot taken with my 90mm lens on my M3, the man is a salesman at Classic Camera in London where I bought the lens, this is a test pic. Click on the pic and you can see the pores on his nose! I was really pleased and can understand why people will pay more for Leica.
I am going back to film for all my personal work and have also bought a Nikon F3 for slide work. I am so pleased about digital! Thanks to it some of these great cameras and lens systems are dirt cheap! Not the Leicas unfortunately.
