Panasonic SZ3 vs Pentax K-7 Sensor Comparison

Generally, it can be tough to visualize the gap in sensor dimensions simply by checking out a spec sheet. The picture below might offer you a stronger sense of the sensor dimensions in the SZ3 and K-7.

As you can see, the two cameras enjoy different megapixels and different sensor dimensions. The SZ3 using its smaller sensor is going to make shooting bokeh harder and the Panasonic SZ3 will produce extra detail because of its extra 1 Megapixels. Greater resolution will make it easier to crop photos far more aggressively. The more modern SZ3 should have an edge with regard to sensor technology.
