If I remember right, the Sony "DRO" feature applies to JPEG images only and doesn't actually change the dynamic range of the camera. It just processes the RAW image to optimize and bring out the shadow and highlight detail that isn't visible in an unprocessed image. This feature is available with all DSLRs now under different names.
