I use aperture priority almost exclusively, so I had to check how the camera dials work in different modes on the D90. I don't know how interesting the info below to most Pentax users, but it may help compare the relative easy of use of the cameras.
First, there are two mutually exclusive settings on the D90. Easy ISO lets you use one of the dials to change ISO without pushing a button. Easy EV lets you do the same for exposure compensation. So, depending on how you set these, you need to push a button and turn a dial to change either ISO, or EV, or both.
With Easy ISO set, here's how it works:
- In aperture priority, the front dial controls aperture, the rear ISO
- In shutter priority, the rear dial controls shutter speed, and the front one ISO
- In P mode, the rear dial controls "flexible program", the front dial ISO
- In M mode, Easy ISO does not work. You have to press the ISO button to change ISO
