Pentax X90 vs Sony RX10 IV

Its time to take a closer look at the Pentax X90 and Sony RX10 IV, one being a Small Sensor Superzoom and the other is a Large Sensor Superzoom by manufacturers Pentax and Sony. There exists a sizeable gap among the image resolutions of the X90 (12MP) and RX10 IV (20MP) and the X90 (1/2.3") and RX10 IV (1") provide totally different sensor sizes.

The X90 was introduced 8 years before the RX10 IV and that is a fairly large gap as far as camera technology is concerned. Both the cameras have the same body design (SLR-like (bridge)).

Before getting right into a step-by-step comparison, here is a short introduction of how the X90 matches up versus the RX10 IV with regard to portability, imaging, features and an overall grade.

Here is a sample of the gallery pics for Pentax X90 and Sony Cyber-shot DSC-RX10 IV. The whole galleries are available at Pentax X90 Gallery and Sony RX10 IV Gallery.

In case you're going to lug around your camera, you have to factor in its weight and size.

Do not forget, the weight of an Interchangeable Lens Camera will change based on the lens you select at that moment. Below is a front view measurement comparison of the X90 and the RX10 IV.

Looking at dimensions and weight, the portability score of the X90 and RX10 IV is 69 and 52 respectively.

Quite often, it is difficult to envision the difference in sensor measurements merely by seeing specs. The graphic here will provide you a far better sense of the sensor sizing in the X90 and RX10 IV.

All in all, the two cameras provide different resolutions and different sensor measurements. The X90 having a smaller sensor will make getting shallower depth of field tougher and the Sony RX10 IV will produce greater detail using its extra 8MP. Greater resolution will also allow you to crop photos more aggressively. The older X90 will be behind in sensor tech.
