A57 or A65 for lowlight wildlife?

16 mp should be better at higher ISO...but I've used both and really don't see much difference in noise.

The one useful feature in the A65 is the smart conversion button, it crops the picture to X 1.4 & X 2.0 at lower megapixels.  The clear zoom in the A57 is an digital zoom, interpolation feature which I see as useless.
