Panasonic ZS25 vs Pentax 645Z Sensor Comparison

As you can plainly see, both of those cameras provide different megapixels and different sensor sizes. The ZS25 having a tinier sensor is going to make shooting shallow depth of field tougher and the Pentax 645Z will offer you extra detail because of its extra 35 Megapixels. Higher resolution will also make it easier to crop pictures more aggressively. The more aged ZS25 is going to be behind with regard to sensor tech.
