Help needed: Setting 100 to 200 ISO on a 5D2?

Help - I am having a "senior moment"!

On page 57 the manual of my 5D2 quotes the ISO range as 100 to 6400 but for the life of me I can only see A, then 200-6400.

How I select an ISO in the 100 to 160 range?

I see on page 58 a note that C.Fn II-3 (Highlight tone priority) when set to 1: Enable limits the ISO range to 200-6400 but I've never been anywhere near that function.

You may have highlight time priority selected which limits lower iso to 200

edit sorry only saw top bit originally due using my phone

And you doublechecked that HTP is indeed not turned on by mistake? I can't think of anything else that would cause what you are seeing on a 5D2.

You could try clearing all custom settings to see if that fixes it.

Indeed your are right. While I have never been anywhere near that custom function thats exactly what was preventing me selecting a lower ISO than 200. That does not mean that others have not of course, because a couple of times I've let others fiddle with the camera (and regretted it subsequently!)

My grateful thanks to you both.
