the difference between two 4 by 5 _120 mm macro digital lenses

[studio347]

Hi,
Are there any image quality differences between 120mm schneider macro digitar and 120mm Rodenstock(and Sinaron) macro digital lens?
I read that schneider is more 1 : 1 optimized than Rodenstock (1 :2 ?). But other than that, are you seeing any IQ difference if any?

In the schenider 120mm macro digitar lens, I see that the older version has small design difference than the newer schneider 120mm macro digitar. The older one has white line at the metal part of front glass. Are there any differences between these schneider lenses(older and newer versions) other than the white line?
Many thanks in advance.

The Schneider design may be closer to a process design while Rodenstock actually gives a range and it is excellent from 1/2 to at least 2 times life size.
