From I can gather, Kern made one the 50mms which is said to be one the best 50mm for 35mm ever made, but I did not see any others. Agnenieux, Kinopye, Schnedier, Kilfit, Zoomar and even Pentax made Apla lens for Apla, Germany, France, US and Japan. I could find any referance to the 500 to 800 zoom reflex shown in Wikipedia.
