coupling ring

hi
is it possible to get a coupling with
the following threads 52mm to 46mm
external threads
neil

To couple to lenses together?
It's not so a smart move to go from bigger to smaller and 46mm is really smaller so I dont think you will find something.

hi stefan
its not to couple two lenses together
it to couple my lens to a digiscoping adapter

You can get all sorts of stuff on ebay, usually from China. I've just got a ring that lets me use 39mm Leica thread enlarger lenses on a 42mm Pentax screw to K adaptor, so that I can use enlarger lenses on a bellows.

You may have to make it up with 2 or 3 rings.

ah okay that explains a lot
Shim have already said it, you might need to buy a step down ring to get to the right sive of the coupling ring
