Consists from Manfrotto 300N rotator (sorry, Nick ), lower rail from NN3 (light and compact) and vertical assembly from NN5.

The greatest advantage of using Manfrotto 300N (the only piece o panor amic equipment produced by Manfrotto worth to have) is flexibility - I can shoot with Nikkor or Sigma without disassembling rotator and switching from 4 to 6 around on the fly. Also food for shooting semi-pole panos with te monopot mounted on the tripod (on te 300N again).

Who can share their modifications?
