Olympus 550WP vs Pentax K-01 Sensor Comparison

Often, it is very hard to visualise the difference between sensor sizing purely by reading through a spec sheet. The visual here will help provide you a better sense of the sensor measurements in the 550WP and K-01.

As you can see, both of those cameras enjoy different megapixel count and different sensor sizing. The 550WP because of its tinier sensor will make shooting bokeh more difficult and the Pentax K-01 will resolve more detail having its extra 6MP. Greater resolution can also help you crop pics far more aggressively. The older 550WP is going to be disadvantaged in sensor tech.
