or do i?
i'm thinking of swapping my 1D3 for a 7D(plus some cash) and since this is my birding camera, what do you guys think about it? i'm thinking the smaller sensor and extra pixels would be a benefit, however would there be an increase in image IQ? my main lens for bird shooting is a 400mm f/5.6 ,and a 70-200 f/2.8, both Canon.
