Hi Pentaxian friends.
The (P) mode is not a new mode on the K-7, but because of the information displayed differently on the new 3" LCD monitor, it gives the (P) mode a whole new twist. The (P) Hyper-Program Mode let's you decide if you want to shoot Aperture Priority, Shutter Priority, Sensitivity Priority, or whatever the camera decides is best using the Program Line. The Program Line has six different choices that can be preset in the Rec Mode. The preset lines are: Auto, Normal, High Speed priority, DOF deep, DOF shallow and MTF.
Once you turn the camera on, while in "P" mode, you will see the following screen:
If you rotate the rear e-dial, the mode becomes Av (Aperture Priority):
If you rotate the front e-dial, the mode becomes Tv (Shutter Priority):
With the new dedicated "ISO" button, you press it and change the ISO using the rear e-dial. Now the camera mode essentially turns to Sv (Sensitivity mode) although the ISO will remain at that setting until you manually change it, even when the green button is pressed.
If you want to come back to the camera (P) settings, just press the green button.
If that weren't enough, you can change the EV compensation by a factor of +5 or -5, by pressing the dedicated EV Compensation button. All the above changes can be made without going through pages and pages of menu-driven functions.
The (P) Mode could be the only mode available and the K-7 would still be a great camera.
