After years of releasing mirrorless cameras without a clear direction, Sony got it right: they put a APS-C sensor on all of their mirrorless line.
Being disappointed by the Sony A57 DSLT, I have bought a NEX3N with a 16-55mm kit lens, that sells for about 400 euros. It does not shoot 12fps or nothing like that, but it has an overall better quality at shooting photos than the A57. And the ISO does not go bananas every time. And that is all that counts.
Sure, it has focus problems, especially with zoom lens (I have tested a 18-200mm lens), but that’s a tradeoff I am willing to make.
