This doesn't work in Manual mode. The Pentax engineers are right- one can already see the ISO on the rear screen, and the most important issue when shooting in the Manual mode is to adjust for correct exposure manually, for which the camera's meter reading display is essential to see. There is only so much room available in the VF. However, it is possible to replace one reading with another, and in this case it is the horizontal leveling display. On my KP this is activated or deactivated with a button on the camera body- quick and easy to do. My K-S2 does not have the advanced controls of the KP, so you have to go into menus to find the horizontal level display to turn it off. Then the room taken up by this display will now sport a graph indicating the camera's meter reading, which I prefer anyway, so the spot for ISO is then returned to that purpose.
Missing then is the leveling indicator. Choose which you would prefer to be missing! Keep in mind, with leveling shown, one can get a better idea of how the camera is tilted to best advantage, and still verify ISO on the rear screen! At least the choice is there.
