Pentax E85 vs Sony RX10

Below is a complete comparison of the Pentax E85 versus Sony RX10, one being a Small Sensor Compact and the latter is a Large Sensor Superzoom by competitors Pentax and Sony. There exists a big gap between the resolutions of the E85 (12MP) and RX10 (20MP) and the E85 (1/2.3") and RX10 (1") feature different sensor measurements.

The E85 was introduced 5 years prior to the RX10 and that is quite a big gap as far as technology is concerned. Both cameras come with different body type with the Pentax E85 being a Compact camera and the Sony RX10 being a SLR-like (bridge) camera.

Before diving through a step-by-step comparison, below is a quick view of how the E85 matches up versus the RX10 in the way of portability, imaging, features and an overall grade.

The following is a preview of the gallery images for Pentax Optio E85 and Sony Cyber-shot DSC-RX10. The whole galleries are available at Pentax E85 Gallery and Sony RX10 Gallery.

When you are intending to lug around your camera regularly, you'll have to think about its weight and measurements.

Keep in mind, the weight of an Interchangeable Lens Camera will differ depending on the lens you are working with at that moment. Here is the front view over all size comparison of the E85 vs the RX10.

Taking into account dimensions and weight, the portability rating of the E85 and RX10 is 95 and 58 respectively.

Normally, it can be hard to imagine the gap between sensor measurements just by reading specs. The graphic below might give you a clearer sense of the sensor sizing in the E85 and RX10.

All in all, the 2 cameras have got different megapixel count and different sensor measurements. The E85 using its tinier sensor is going to make shooting shallower depth of field trickier and the Sony RX10 will offer you greater detail using its extra 8 Megapixels. Higher resolution will also allow you to crop pictures much more aggressively. The older E85 is going to be disadvantaged with regard to sensor technology.
