A major factor in the D300’s stellar image quality is the new Sony-made 12.3MP (effective) CMOS sensor that captures RAW data with up to 14 bits of color per red, green, and blue channels. Most other DSLRs in this class only provide 12 bits per channel. This gives the D300 an advantage in reproducing fine color gradations, shadow details, and wider dynamic range. But it also increases the file size of images recorded in the 14-bit mode (selectable over normal 12-bit RAW).
