Changing ISO levels

bass3587 · 06-25-2013, 05:25 AM

I need some help. For the life of me I can't seem to find where I can change the settings for my ISO levels. I have the K5 and I know you can push the ISO button on the top of the camera to get into the ISO mode but it's the levels I'm having a problem with. When I start changing the levels the only options I'm getting are 80, 100, 200, 400, 800, 1600, 3200,6400, 12800, 25600 and 51200. I'm not able to choose any other level like, 300, 500, 640 or any other ISO level like I can on my KX. Did I change a menu selection by accident? I would like to be able to choose a different ISO level other than those options as noise levels are really an issue going from 1600 to 3200 when 2000 would be just fine.. Any help would be appreciated.

Menu > Custom Settings > 1 'EV steps' and 2 'Sensitivity Steps'
(Pages 95-96 and p-120 of the K-5 manual).
It's identical to the K-x.

There's a menu setting that keeps ISO at whole stops (like you have now) or uses the same steps (1/2 or 1/3) as your exposure.
