Obviously C,3 Expanded Sensitivity is where I have to go and I have that set to "ON"
But when I depress the ISO button and scroll the rear dial - the lowest setting that shows up in the top display is 200
I am open to any and all suggestions, this is a brand new camera from Adorama and I'm hoping this isn't some sort of malfunction
Thanks.
Not sure (mine will go to ISO100) - have you got the latest firmware installed?

That
should not explain it, as the function has worked since the first version of the firmware, but always good to exclude this possibility just in case something weird is going on.
