Notes & Features: Sony's D-Range Optimizer to retrieve picture detail in photos with harsh highlights or dark shadows; semi-manual focus that allows you to select the focusing distance based on your subject's location; an improved auto focus system that includes macro ranges; Super SteadyShot image stabilization; high sensitivity settings up to ISO 3200; and in-camera editing functions such as "unsharp mask" to sharpen images. Sony's "smile shutter" mode, which automatically captures an image when your subject smiles -- without having to press the shutter. This function even lets you prioritize adult or child faces to capture photos only when the intended subjects smile.
