Body Elements

On the top right of the K-5's rear is the rear control dial, and just to its right the AE-L button. Beneath the rear control dial is a green button which serves two purposes - to instantly set aperture and shutter speed for the correct metered exposure in manual mode, or to return to regular program mode from Hyper-Program mode (see the operation and controls section of this test for more information).
Just beneath the green button is the K-5's AF pattern selection switch. We really like physical switches for AF, and fortunately the K-5's AF switch is stiff enough not to be jogged accidentally. Here, you can select from automatic AF point selection, manual AF point selection, and fixed centre AF point.

The 'AF' button in its centre can be used to initiate autofocusing, as an alternative to half-pressing the shutter.
Beneath the AF switch is a cluster of buttons which provide access to key shooting parameters - self-timer, white balance, flash and color/contrast/sharpening settings.

'LV' stands for live view. Sadly, there is no shortcut from live view shooting to video shooting - you have to rotate the exposure mode dial.
Another AF mode switch, this one for continuous, single-servo (AF-S) or manual mode, is positioned on the lower left-hand side of the K-5's lens mount.
The RAW / Fx (which stands for 'Flex') button sits above the AF switch, and can be assigned to one of five possible functions - one push file format, exposure bracketing, digital preview, electronic level, or composition adjust.

Composition adjust uses the X-Y axis movement of the sensor (used for shake reduction) to allow very precise fine-tuning of framing.
Above the RAW/Fx button is the flash button, which activates the inbuilt pop-up flash unit, and beneath it the PC flash sync socket, concealed by a screw-in cap.
A single SD card bay is concealed underneath a slide-to-lock door on the right-hand side of the K-5, within the grip.
