I should add except for the A900 owners the rest of us are at a disadvantage to a full frame sensor. Also Sony lacks a little in higher ISO setting compared to that other brand he uses.
With my old A100 I was very happy with ISO 400 or 800 at shutter priority 1/1600 with a 2.8 lens. I will be experimenting with higher ISO with my A700 which so far I see much better results than the A100. What he taught me was a different way of thinking towards shutter speed and compensating ISO. Were I was used to always trying to keep the lowest ISO possible and sacrificing shutter speed even if it meant blur.
