So who´s buying the 70d if the ISO performance is the same as 60d´s (or a small improvement)?
That would most likely be me. As the owner of an aging 40D, I would like to add video, some more pixels, and increased ISO from the 3200 max I have now. Even if the IQ isn't much better than the 60D, it is still better than the IQ of the 40D.
Budget will probably keep the 7D II out of reach. FF is also out of the question due to the added expense of getting new lenses, and a speedlite.
