Plainly, both cameras enjoy different resolutions and different sensor sizing. The CX1 due to its smaller sensor is going to make achieving bokeh more challenging and the Sony A55 will render more detail having its extra 7MP. Higher resolution will also make it easier to crop shots far more aggressively. The older CX1 will be behind with regard to sensor tech.
