Panasonic LX100 II vs Pentax 645Z Sensor Comparison

Quite often, it's difficult to see the gap between sensor sizes simply by reading through a spec sheet. The picture underneath will help offer you a far better sense of the sensor sizes in the LX100 II and 645Z.

As you can see, both of the cameras come with different resolutions and different sensor sizes. The LX100 II with its tinier sensor will make getting shallow depth of field more challenging and the Pentax 645Z will give extra detail because of its extra 34 Megapixels. Greater resolution will also allow you to crop images a good deal more aggressively. The newer LX100 II is going to have a benefit when it comes to sensor technology.
