I can give you a different view on their lenses.
Back in the 70s I was the Product Manager for Beseler enlargers. Schneider had redesigned the Componon lenses so that physically the barrel obstructed the built-in filter drawer on the Beseler enlargers (45 and 23). As we were distributing the lenses from Schneider at that time and were one of the largest distributors of Schneider lenses in the USA we were rather surprised when we began receiving complaints that the filter drawer could not be used and were even more surprised to discover that Schneider had not informed us that they were making a change.
To be able to continue to distribute a premium, high quality, enlarging lens series from 50 to 135mm we started to test other options. Since Rodenstock in those days was distributed by Berkey Photo Marketing - the manufacturer of our biggest competitor - Omega, we began to investigate and test lenses from Japan.
When we tested the Komurnon lenses they easily outperformed the Componon lenses of th same era. We became the Komura distributor for their enlarging lenses and discontinued Schneider lenses.
If their taking lenses for LF were as good as their enlarging lenses then they should be the equal of the other symmetrical - convertible - lenses of that same era. The Symmars and the Sironars. But compared to current lenses they would not be as good as an Apo Sironar-S or Schneiders last lenses.
