Mirrorless interchangeable-lens cameras (MILCs) combine large sensors and the ability to swap lenses into small, stylish bodies that you don't mind carrying. This 16-megapixel model might be the most versatile one ever: It has the fastest autofocus of any MILC, the world's first five-axis image stabilization, and a tap-to-focus touchscreen.
