Plainly, both of these cameras have got different megapixels and different sensor sizes. The FE-45 because of its tinier sensor is going to make shooting shallow DOF more difficult and the Sony A57 will resolve more detail utilizing its extra 6 Megapixels. Greater resolution will make it easier to crop images much more aggressively. The more aged FE-45 is going to be disadvantaged in sensor innovation.
