Usually, it can be tough to visualise the contrast between sensor dimensions merely by reviewing technical specs. The image here might give you a stronger sense of the sensor dimensions in the 645D and ZX1.
As you can tell, both cameras feature different resolutions and different sensor dimensions. The 645D featuring a larger sensor will make shooting shallow depth of field less difficult and the Pentax 645D will deliver greater detail utilizing its extra 3 Megapixels. Greater resolution can also make it easier to crop pics way more aggressively. The more aged 645D is going to be disadvantaged in sensor innovation.
