Panasonic LZ20 vs Pentax 645Z Sensor Comparison

Usually, it can be hard to picture the difference between sensor dimensions merely by looking at specifications. The picture here might give you a far better sense of the sensor dimensions in the LZ20 and 645Z.

Plainly, both the cameras feature different megapixels and different sensor dimensions. The LZ20 with its tinier sensor is going to make achieving shallow DOF tougher and the Pentax 645Z will give you more detail with its extra 35 Megapixels. Greater resolution can also enable you to crop pics way more aggressively. The more aged LZ20 is going to be behind when it comes to sensor innovation.
