Hello, my minolta srt 101 lens diaphram was sticking (rokkor 1.7 f=55mm) I read on this forum that grease on the diaphram blades was most likely the problem. I found the minolta service manual on the web and disassembled the inner barrel and cleaned the diaphram blades. I lost one setscrew (seem to work with just two). The service manual says to use a "minumum diameter position determing jig" which of course I dont have. I set the f16 diameter of the blades to 24mm * 1.7 / 16 = 2.55mm where 24 mm was what I measured for the max diameter of the diaphram (f1.7) is this about right?
