Panasonic FX90 vs Pentax K-3 Sensor Comparison

Generally, it's difficult to imagine the gap in sensor sizes just by seeing specifications. The picture below might give you a far better sense of the sensor measurements in the FX90 and K-3.

Plainly, both of those cameras come with different megapixel count and different sensor sizes. The FX90 having a smaller sensor is going to make achieving shallower DOF trickier and the Pentax K-3 will produce greater detail because of its extra 12MP. Higher resolution will let you crop pictures a good deal more aggressively. The more aged FX90 will be disadvantaged with regard to sensor innovation.
