All in all, both the cameras come with different megapixel count and different sensor sizes. The E-M1X featuring a tinier sensor will make achieving shallow depth of field more challenging and the Sony A850 will resolve extra detail as a result of its extra 5MP. Higher resolution will also help you crop shots a good deal more aggressively. The fresher E-M1X will have a benefit with regard to sensor innovation.
