i think it is called "coupling ring" which 2 side are filter threads ... so far I could not find it here ...

I use 1 step-up ring and 1 step-down ring to create the above.

for e.g. if u wanna mount a camera with lens 49mm filter thread to a 50mm lens with 52mm filter thread ,

get a step-up ring 49mm-55mm
and a step-down ring 55mm-52mm

thanks....megaweb......but i still don't get it
won't you end up with the same problem after stacking the 2 stepping rings? ie. you still won't get a threaded ring on the outside which you can screw the reveresed lens in.
