Sigma SD15 vs Sony RX10 IV

Its time to take a closer look at the Sigma SD15 and Sony RX10 IV, one being a Advanced DSLR and the latter is a Large Sensor Superzoom by manufacturers Sigma and Sony. There exists a sizeable gap between the resolutions of the SD15 (5MP) and RX10 IV (20MP) and the SD15 (APS-C) and RX10 IV (1") enjoy totally different sensor sizes.

The SD15 was introduced 8 years before the RX10 IV and that is quite a large gap as far as technology is concerned. Each of the cameras come with different body type with the Sigma SD15 being a Mid-size SLR camera and the Sony RX10 IV being a SLR-like (bridge) camera.

Before delving in to a in-depth comparison, below is a short highlight of how the SD15 matches up against the RX10 IV with regards to portability, imaging, features and an overall grade.

Following is a preview of the gallery photos for Sigma SD15 and Sony Cyber-shot DSC-RX10 IV. The whole galleries are available at Sigma SD15 Gallery and Sony RX10 IV Gallery.

If you are planning to lug around your camera frequently, you need to consider its weight and volume.

Always remember, the weight of an Interchangeable Lens Camera will differ depending on the lens you use at that time. Underneath is the front view over all size comparison of the SD15 compared to the RX10 IV.

Looking at dimensions and weight, the portability grade of the SD15 and RX10 IV is 59 and 52 respectively.

Normally, it is hard to see the contrast between sensor measurements purely by looking at technical specs. The graphic here will provide you a clearer sense of the sensor sizes in the SD15 and RX10 IV.

As you have seen, the 2 cameras have got different megapixels and different sensor measurements. The SD15 with its bigger sensor will make getting shallower DOF less difficult and the Sony RX10 IV will resolve extra detail using its extra 15MP. Higher resolution will allow you to crop photographs much more aggressively. The older SD15 is going to be behind in sensor innovation.
