Pentax Efina vs Sony RX10

Below, we are reviewing the Pentax Efina versus Sony RX10, one being a Ultracompact and the other is a Large Sensor Superzoom by brands Pentax and Sony. There exists a crucial gap between the resolutions of the Efina (14MP) and RX10 (20MP) and the Efina (1/2.3") and RX10 (1") enjoy totally different sensor measurements.

The Efina was unveiled 9 months earlier than the RX10 so they are both of a similar generation. Each of these cameras come with different body type with the Pentax Efina being a Ultracompact camera and the Sony RX10 being a SLR-like (bridge) camera.

Before delving straight into a in depth comparison, below is a simple view of how the Efina matches up vs the RX10 with regard to portability, imaging, features and an overall grade.

This is a sample of the gallery pics for Pentax Efina and Sony Cyber-shot DSC-RX10. The full galleries are available at Pentax Efina Gallery and Sony RX10 Gallery.

For those who are aiming to lug around your camera regularly, you will have to take into account its weight and proportions.

Typically, it is hard to visualise the contrast between sensor measurements merely by reviewing technical specs. The visual here will help offer you a far better sense of the sensor sizes in the Efina and RX10.

As you can tell, each of these cameras posses different megapixels and different sensor measurements. The Efina using its tinier sensor will make achieving shallower DOF more difficult and the Sony RX10 will deliver greater detail having an extra 6 Megapixels. Greater resolution will help you crop pics somewhat more aggressively. The older Efina is going to be behind with regard to sensor tech.
