You can also disassemble the rear of the lens, remove the aperture ring, grind or file a new notch somewhere between 1.2 and 2, then re-install the ring and reassemble.
Voila! f1.5 (or something like that) which gives the best of both worlds between f1.2 and f2 on the Rokkor 58/1.2
+1
there is barely room for two new notches in between f/1.2 and f/2 if you can be precise.
it\'s always been a pet peeve of mine about rokkor lenses that there no stop between wide open and the next full stop while everything else is in have stops.
