For me, the High Iso performance test requires 1) take a photo of people in 2) indoor sport arena, theater or other dim (low light) environment, with 3) dark shadows in the background.

I love it when people make statements such as "useable at ISO6400" re full-frame cameras! Well, it better be. If "decent pictures can come out of my a57 at IDSO3200, the a99 better be outstanding at ISO6400 or higher. It is, after all, a much bigger sensor costing almost 4x as much!
