DK on the a99

I disagree. If you look at the times when you will most likely be using higher iso, this is in low light shooting. This is also when you will need fast glass, but we are talking about a camera that cannot use AF if you need faster than F3.5 right? So in low light, there is a distinct disadvantage. As for DR, it drops considerably when high iso is used, and a quick look at DXO shows the a99 is not the high iso DR leader, although the 5DIII is pretty good. The a99 is a great tool for good light video if you don't care about sharpness, but we shouldn't kid ourselves, sharpness is important. If it wasn't, we wouldn't have blue ray and HD channels.
