There's no need for a dedicated ISO button, because you have two dedicated ISO modes on the mode dial.

Sv - Sensitivity priority

You change the ISO and look at the value in the viewfinder. The camera sets the aperture and shutter combination that matches the sensitivity. The logic behind the aperture and shutter selection is defined in Pentax program lines, they weren't listed in the specs but in previous cameras they have been - Standard, DOF, Action and MTF-program.

TAv - TimeAperture priority

Instead of first selecting ISO and then changing aperture and shutter to match this ISO, this works the other way around. You set the aperture and shutter, the combination you want, and the camera sets the ISO that gives a correct exposure for this aperture and shutter combination. There's no need to press the ISO button.

So you see, why would you have a ISO button? It would just complicate things. Pentax has saved you a button press here. Thank you Pentax.

The Fn button and the OK button is customisable, but exactly what functions you can have there is as yet unknown. We have to see the user manual for that.

Take care
