Medium format cameras have a much greater area sensor and probably overall better quality ($2,000 vs $20,000 or even $50,000 medium format camera) compared to a regular digital DSLR camera. Even a quick Google seemed to indicate photographers prefer the larger sensor size even if it has fewer pixels.
The article mentions "face images retrieved from eye reflections need not be of high quality in order to be identifiable" but even so there must be a massive difference in picture quality compared to a Hasselblad medium format camera sensor.
Still interesting though it's as if the goofy CSI or Blade Runner "Enhance!" has come true.
