I've tried finding some articles/reviews comparing these two. I'm curious as to the quality difference when facetiming between say an Ipad Mini with a 1.2 facetime camera vs say a Ipad pro 9.7 with the 5 megapixel. The devices on the other end will likely be an Iphone 6 and or Iphone 6S. I understand the 6 has the 1.2 and the 6S has the 5. Thoughts?
