Notes 

  • When fitting a DSLR camera you need only a M48 Ring to suit your Canon or Nikon camera. No spacers are required.
  • The spacing for dedicated CCD imaging cameras is 54.9mm from mating surface (75mm from centre of rear element). 
  • The rear thread is M48. When using T-threaded accessories you will need a FLO M48-T adapter.
