And neither does a reversing ring.
What I have used to stop down a lens in such situations are those
springy-metal pants-cuff clips for cyclists. You place it around the lens
mount over the depth-of-field preview button, and it stops down the lens.
Twist it a quarter turn to open the diaghram.
The very cheapest ones are bare metal, and may scratch. You could paint
them with the stuff used to coat tool handles, or you could slip some
plastic tubing over them to avoid this. I've seen more expensive ones that
are fabric covered.
