Hi Robert
I owned a small Moviecam set a while back and the 14mm was most likely a Canon 14mm (I have the Optex version of the Canon as well to compare). The 85mm had a canon imprint on the lens cap, as the K35s did (picture attached) so not sure about that being Zuiko?
I never had the 17mm but my understanding was that it was a Zuiko 21mm F2.0 that the rear group had been spaced further back to expand. It was discussed by Stephen Gelb here:

where another user also says he reached out to Moviecam and had it confirmed the 17mm and 20mm were Zuiko glass.
