Historically, all cameras worth their salt have had PASM, meaning Program, aperture-priority, shutter-priority and manual. With this camera, Pentax have gone one step further with what I am going to call PASIM as they have added a very sensible ISO priority setting. Pentax are calling it sensitivity-priority but we generally know of it as changing the ISO setting. In fact, there are two versions of the sensitivity mode, one selecting both the shutter and aperture for you, while the other, called shutter & aperture mode, allows selection of the shutter and aperture while optimising the ISO for you.
