The A700's new Exmor CMOS sensor maximizes the performance potential of the α lens lineup with 12.24- megapixel resolution that's rich in highlight and shadow detail. Because proprietary Sony noise reduction technologies are applied right on the Exmor CMOS sensor itself, signal output is exceptionally clean even at sensitivity settings as high as ISO 3200. In addition, a 3-layer low pass filter preserves high-resolution detail while suppressing moiré effects and color artifacts.
