On a purely visual level the 35/2 asph has negative front and rear elements while the 40/2 has positive front and rear elements. The 35/2 asph also has an aspheric lens element which greatly assists in the correction of aberrations. This not to say that the 40/2 is not a good lens but just that the 35/2 asph is even better wide open. The 35/2 asph is even heavier than the 35/1.4 asph! > From: John Coan <jcoan@mindspring.com> > > I just received a 35 Summicron-M Asph today. I already had a 40 > Summicron-C.
