Erik, the Componar-S is quite a different lens to the Comparon-S, Schneider could have used a better naming scheme to differentiate between these lenses.

Componon & Componon S 6 elements.
Comparon & Comparon S - 4 elements
Componar S - 3 element - budget triplet lens

The Componar is actually a good performer despite being a triplet, corners sharpness isn't that good until stopped down and it was designed and sold as a budget lens.

Componons were made in all sizes up to 360mm, Comparons up to 300mm, but the Componar was restricted to 50/80/105mm.
