Old Nikon manual Vs Leica R primes for BMCC EF

Would Old Nikon manual or Leica R glasses with suitable adapters be good choice for BMCC EF. I have read people using them all over places but couldn't find any video except John Brawley's Puberty blues. There too I couldn't find whether the mount was EF or MFT.
Would the above two glasses be able to hold well for big screen. Are there any other Old/inexpensive glasses which can dream for big screen??
Can someone refer some links for footage using such glasses??
