Quite often, it can be difficult to envision the contrast in sensor measurements only by viewing specifications. The photograph below may offer you a stronger sense of the sensor measurements in the E-1 and 645Z.

Plainly, both of those cameras feature different megapixels and different sensor measurements. The E-1 having a smaller sensor will make getting bokeh tougher and the Pentax 645Z will provide you with extra detail using its extra 46MP. Higher resolution will let you crop photographs way more aggressively. The older E-1 will be disadvantaged when it comes to sensor tech.
