The Schneider and Rodenstock 135 and 150 all are available as six element lenses. Both Schneider Componon-S (135mm and 150mm) have excellent MTF for moderate 4x5 enlargements and have similar image illumination at the corners.

The Rodenstock Rodagon 135mm is $614.95 and the 150mm is $799.95 at B&H.

RED= Schneider Componon-S 150mm
GREEN = Schneider Componon-S 135mm
