As you can see, the two cameras feature different megapixel count and different sensor measurements. The M-Monochrom because of its bigger sensor is going to make shooting shallower DOF easier and the Sony A58 will result in extra detail due to its extra 2 Megapixels. Higher resolution can also let you crop shots way more aggressively. The older M-Monochrom will be behind in sensor innovation.
