There are production stills from A Clockwork Orange showing Kubrick using a BNC (non-reflex) on the record store set. So he used the BNC, ARRI 2Cs with the ARRI blimp (the 400' mag version) and the Cine 60 blimp.
Apart from the previously mentioned Kinoptik 9.8, I don't know what fixed focal length lenses were used, but Cinema Products built Kubrick a zoom lens with a 20-1 or 25-1 ratio based on Angenieux components if I recall correctly (the memory grows fuzzy after 30 years) which was subsequently used on Barry Lyndon.
