Among the GX-10's options are 11-point autofocus selection, unlinked autoexposure and autofocus, and mechanical (sensor shift) image stabilization. The Fn button pops up a display for changing ISO sensitivity, drive mode, flash mode, and white balance.
Sliding the power switch toward the aperture icon will provide either a depth-of-field preview through the optical viewfinder or a scene preview on the LCD. That green-dotted button controls program shift in manual and semimanual exposure modes.
The kit lens produces nicely sharp details, but the GX-10 routinely meters toward underexposure. This photo was shot with the Pentax AF-540FGZ external flash, using spot metering, and I still had a hard time getting the brightness up.
