I was planning to get this camera after waiting for something better than the A80 to come out. Dang. Now I want to the the a85 because it is cheaper (and i know it is the upgrade for a70), but ppl say that the imager is too small and there is too much noise. ppl also say that there is purple fringing on the a85 (and a95). so is a85's lack of swivel LCD and small imager so bad?
