   AR series - Threaded Metal Step-up Rings


  • These adapter rings screw onto the lens' front filter thread.  

  • The thin rings are best for when a rods support system is being used.

  • The medium-thick rings are best for clamp-on use.

  • The offset rings are recommended for clamp-on use when using wider angle DSLR lenses, as they will allow the matte box to sit further back in relation to the lens front (the deep rings especially are useful for this purpose). 

  • The conical rings are intended only for special purposes (ie if the camera has a low overhanging microphone and the matte box needs to be pushed out further in front of the lens).
