Thanks again Suzanne,

Re: the real estate, I am saying to compare the optic quality difference, eliminate that variable by printing only from a 35 mm size out of the 120 film from whatever camera to compare.

I agree and concur with all of the above posts. I like the look of 35mm for a lot of work and of course the ease and speed of using. Short of scientific tests ( Emile mentions the tests on the DR 50) what is the mystic? is it really there- the secret formula for the Leica/Contax? Can we actually see it and compare.

I like to look I get with my old nikon 35 for my street and I am still shooting with 30 year old Pentax bodies and lenses-for other work I use 8 x 10, and I will own a Leica one fine day.
