Pentax P80 vs Sony RX100 III

Lets take a deeper look at the Pentax P80 and Sony RX100 III, former being a Small Sensor Compact while the other is a Large Sensor Compact by companies Pentax and Sony. There exists a sizable gap among the resolutions of the P80 (12MP) and RX100 III (20MP) and the P80 (1/2.3") and RX100 III (1") come with different sensor measurements.

The P80 was introduced 5 years before the RX100 III and that is a fairly significant difference as far as camera technology is concerned. Each of the cameras offer different body type with the Pentax P80 being a Compact camera and the Sony RX100 III being a Large Sensor Compact camera.

Before diving through a comprehensive comparison, below is a simple overview of how the P80 matches up versus the RX100 III in terms of portability, imaging, features and an overall rating.

Quite often, it is very hard to picture the contrast in sensor sizing only by seeing specifications. The photograph below might give you a more clear sense of the sensor sizing in the P80 and RX100 III.

To sum up, the two cameras enjoy different megapixel count and different sensor sizing. The P80 using its smaller sensor is going to make getting shallower DOF harder and the Sony RX100 III will provide more detail using its extra 8 Megapixels. Greater resolution will make it easier to crop images far more aggressively. The older P80 will be disadvantaged in sensor innovation.
