You'd be better off using enlarger objectives rather than cine primes. Something like a Rodagon can nearly compare to a Zeiss Luminar or Leitz Photar. Most cine primes don't work well in close-ups and should I ever have need to do macro cinematography I'd probably rig up a focusing mount (Zoerkendorfer makes these for still cameras) for an L39 enlarging objective (and then experiment with my various models and lengths to find an "optimum" for my application). Both Rodenstock and Schneider even made special versions of their "enlarging" objectives for use in macro work. There is even a variofocal (Schneider Betavaron) available. Any of these bits of "darkroom glass" should be cheap.
