Recently got this 18mm ScopeTronix EP, came with an extra rubber ring that I understand is part of the system but I'm curious about its exact application. 

 

I know this and the other focal lengths of this EP were designed with eyelens bezels that unscrewed to reveal 28mm threads so one could directly attach it to some models of Nikon CoolPix digital cameras, like the old 900 series. 

 

And I've seen mention of the second rubber ring as used for adapting the EP to other cameras but I'd like to know how that works. 

 

Thanks

Actually no, as mentioned I was aware of the 28mm threads that screw into the filter threads of old Nikon digital cameras. 

 

What I want to know is how the secondary rubber ring is used to "...attach to other cameras".

Well I've partially answered my own question, found the bolt case for this amongst the other stuff I got in this buy and it has a little tag with even littler type on it that reads: 

 

"When used with an intermediate adapter install the rubber spacer over the threads. Failure to follow these instructions could cause the lens to contact the eyepiece!".

 

I say 'partially' because I'm having a hard time imagining the scenario they're describing, so still not clear to me.
