Some candidates:
The Meyer Goerlitz (later Pentacon) 4/300 mm and 5.6/500 mm lenses made in East Germany are preset lenses. Then again, with those large diaphragms made of 23 blades one wouldn't expect much else. They're both available with M42. Indeed they have exchangeable mounts for Pentacon 6, M42 and Exakta. My 4/300 mm even has a 'real' PK mount. Ralf -- Ralf R.
