To enable auto ISO simply press the green button together with the ISO button.
Just after I typed this question I picked up the K-1 again and thought to myself 'there must be a way to do it!', and lo-behold I stumbled upon it (somewhat).
Believe it or not I have never really used the dedicated ISO button (near the shutter button), I forgot it was there! Instead I have most of the time had that other wheel set to ISO and used the other wheel near thumb to change the amount.
However, as you say you can set to Auto ISO if you first push ISO and then the Green Button afterwards.
So, what I noticed was this.
- With the FA50mm attached, setting to Auto ISO it didn't want to drop below 1/80th. My Program Line I set as the DoF icon (the one with the blurry background).
- I went and changed the Auto ISO settings from the middle to Slow, and it now didn't drop below 1/40th.
- Changing the Auto ISO to Fast settings and now it didn't want to drop below 1/160th.
Cool... so that's something at least, a choice of 1/40th, 1/80th and 1/160th with a FA50mm attached.
Now to see if it says anything different with a 100mm attached.
PS: Oh and I had SR off, tho when I toggled it on it didn't seem to make any difference to those values changing...
EDIT: And here are the values for using a 100mm lens, Normal = 1/125th, Slow = 1/60th and Fast = 1/250th
Now the question is... is there a shortcut way to set the Auto ISO Parameters to being more easily accessed than the Main Menu (such as pressing the Info button), I can only see options for actually setting the min and max ISO values being bindable but not the actual parameters (Slow, Normal, Fast etc).
