I just obtained a Miranda DR to go along with a Miranda A I have, and unfortunately the lens' aperture mechanism is shot. Attempts to revive it proved futile. So, I'm looking to see if anyone here might have a Miranda or Soligor branded lens with a PAD (pressure activated diaphragm) -- the little sidearm, similar to those on Exaktas, that presses the shutter button on the camera. This isn't my photo, but illustrates what I mean. Thank you!
