Notes & Features: Rear-panel LCD is a touch-panel with gesture support and haptic feedback. You can mark an X on an image to delete it, or an O to rotate it. When an on-screen button is touched the screen vibrates gently as a form of tactile confirmation. Also has "hidden" secondary low-res 1.5", 61,000 dot LCD touch panel on front of camera which is used as a viewfinder for self portrait modes, and can also show a timer countdown, the camera's key settings, a "Smiley" prompt for the Smile Shutter feature, or an animation to attract a child's attention and have them look at the camera. Improved sensor-shift shake reduction (up to 4.5 stops), new Pixel Shift Resolution mode (4-shot composite provides full color information at each pixel and reduces noise), built-in GPS with ASTROTRACER and electronic compass.
