Panasonic ZS45 vs Pentax K-3 Sensor Comparison

Sometimes, it is hard to see the gap between sensor sizing only by looking at technical specs. The graphic here should give you a far better sense of the sensor dimensions in the ZS45 and K-3.

As you can tell, both the cameras enjoy different megapixels and different sensor sizing. The ZS45 due to its tinier sensor will make achieving shallower depth of field more difficult and the Pentax K-3 will resolve extra detail as a result of its extra 8 Megapixels. Higher resolution can also enable you to crop photographs far more aggressively. The more modern ZS45 is going to have a benefit in sensor technology.
