Super-A half stop exposure compensation

I just shot my first role with newly acquired Super-A and found that I need to overexpose by half stop. However, Super-A only allows to compensate by +/- 1,2. Is there anyway I can set to always over-expose by half stop?

Thanks

Unfortunately it's can only adjust in full stop, so it wont work.

Actually, you can set film speed in 1/3 stop increments... but this of course means you don't actually get 1/2 stop: you get a choice if 1/3 or 2/3 stop adjustment...

Change the ISO of your film by hand. So if you shoot 400 and need to overexpose, move the ISO dial one dot before 400 that is a 1/3 increment or 2 dots 2/3rds

Unfortunately the mid-way markings are not effective as per the manual

I do not have the ProgramA or SuperA anymore.... but i'm 99% sure they worked....
I think you are refering to half stops in the lens, not in the ISO setting

I have the Super Program (Super A) and can confirm that:
  • Exposure compensation +/- 2 stops in 1 stop increments
  • ISO settings are in 1/3 stop increments and that the readings at each index mark are consistent with a 1/3 stop increment
The manual does include the text, "The midway markings are not effective", but I believe this means that attempting to set the scale to other than an indexed click stop will not work.

Example:
There are two indexed dots between ISO 100 and ISO 200
ISO 100 ==> ISO 200 = 1 full stop
ISO 100 ==> ISO 125 (first dot) = 1/3 stop
ISO 100 ==> ISO 160 (second dot) = 2/3 stop
FWIW, in practice there are very few cases where one would want to apply less than 1 stop of exposure compensation.

Edited since I just saw your rather remote location, I was going to say send it to Eric. You are likely due for a good CLR so I would recommend just having it done if you can find someone competent.

Thanks, it's difficult to find someone repairing film camera here. Also, except for this problem, camera is in like new condition so hopefully I can live with ISO adjustment. Exposure reading is matching now with my k-x so will update this post after getting next role developed.
