So I have to say I am impressed by the 7D, I thought I would get a marginal improvement at higher ISO's over the A700, but that is not that case, I am genuinely very impressed by the hi ISO performance of this camera, of course the AF is a whole different monster, I got myself thinking, I probably don't need the 5D mark III, the 7D will be technologically (AF, Image processor) ahead of the 5D, so I will stick to APS-C. So now I am thinking instead of the 11-16mm Tokina, 28-75mm Tamron, and some sort of tele. I am thinking about getting a Canon 15-85mm + 100mm f/2.
