Panasonic FS15 vs Pentax 645D Sensor Comparison

As you can see, both of the cameras enjoy different megapixel count and different sensor measurements. The FS15 featuring a smaller sensor is going to make getting bokeh harder and the Pentax 645D will provide more detail as a result of its extra 28MP. Greater resolution will also make it easier to crop images far more aggressively. The older FS15 will be disadvantaged with regard to sensor technology.
