Marvin Moss ==================================================== In a message dated 97-10-17 19:29:48 EDT, you write: << (1) If I remember correct it was mentionend (by Marc and/ or Marvin) some days ago, that the Summitar was produced with different apertures (hexagonal vs. many blades). Do you, or does anybody know, whether both lenses differ just in the management of the strong contrasts (6 vs many rays of the sun's reflections), or do they differ in the management of the out-of-focus areas additionally (because of the different shape of the apertures)? >> Alf
