MarkIII problem

My 1D MarkIII will only go down to iso200. I have checked all of the custom settings and looked in the manual but cannot find an answer to this. Am I missing something? How do I get it to 100 0r 50?

If anyone knows what i'm doing wrong please let me know.

Thanks

You have highlight priority turned on. If so ISO 200 is lowest you get and LCD display will show the ISO as 2oo instead of 200.
It's in the manual btw.

as for iso 50 (L), you have to enable it via cf.n. there are two ways to do it, the easiest is just to set the usable isos from L to H

Yeah I have the CF set to L to H, but I didnt think about highlight priority.

Thanks

AFAIK, there is only 1 way to do this, that's by setting the CFN 1-3 (set ISO speed range).
What is the other method?

HTP is the culprit. Does it look like this 2oo ?
