Just going from memory, since it's been a while since I owned a Jupiter-37A, but you should be safe:
  • It's a manual aperture lens, so no aperture pin to worry about.
  • The rear element is a fair distance up the lens body itself. Since nothing sticks out beyond mount threads, there's nothing to interfere with the open aperture linkage.
thanks for the reply.

i did notice that there was no pin, nothing to interfere, so i screwed it on until it stopped and so now i must harken back to the sunny 16 days of yore, or invest in a light meter

Stopdown metering will work, you just need to stop the lens down manually using the preset lever and the meter switch on the side.
