        The Zeiss 35F2.8 Distagon is about the same size or bigger than the 
         Zuiko 35F2.0 and Canon35F2.0FD.

 And Color Foto and fotoMagazin and Chaseur d´Image and Pop and... have
 different tests.
 I like to alter Churchils say, I don´t believe in lens tests I haven´t
 forged.. aehhm wrote the specifications themself.
 
 Anyway, Zeiss 100mm macro lens for Contax 35mm is known to be an
 excelent lens. During presentation of this lens, Zeiss has declared, the
 lens use no "exotic" type of glas even Zeiss could have used such glas
 if they wanted (made by his daughter company Schott).>>

           I agree--lenses 135 and below don't need LD glass strictly
           speaking! However, the Olympus 100F2.0 uses LD glass and
           floating elements and as a consequence matches or exceeds
           the performance of the larger Zeiss 100F2.0 (67mm filter thread).

 There are good and bad lenses at any manufactors assortment. Even if
 lenses have the same focal lenght they might be optimized for different
 purposes. >>
 
         Agreed!

<< There is no "ideal" lens just "better" and "worse" compromise, depending
 on your intentions.
 
 That is no contradiction to the observation that some manufactors have
 on the average an higher quality level (Zeiss) some an lower level
 (Sigma). Zeiss and Sigma just have different optimising goals (Sigma
 lenses should be cheaper than the one made by the camera makers).

I have high regard for the talents of Zeiss and Kyocera and understand their 
choices and direction! It's just that I prefer Zuiko and Canon FD design 
choices more.
