I have one of the old prewar Biogon 35's (with that scary rear element) and at some time this summer I will run a side by side between the C Biogon 35/2.8 and the oldie. I know that the old one is rather low contrast as it is an uncoated version and, boy can it flare if you are not careful. I will also stick a Summaron 35f2.8 on a M2 and ran these lenses parallell to each other. Could be fun and I suspect that the C Biogon 35f2.8 will sweep the floor in most aspect. It is very sharp with a certain "snap" to it.
