Sigma SD15 vs Sony RX1R II

Here is a in-depth overview of the Sigma SD15 versus Sony RX1R II, one being a Advanced DSLR and the other is a Large Sensor Compact by companies Sigma and Sony. There exists a huge gap between the image resolutions of the SD15 (5MP) and RX1R II (42MP) and the SD15 (APS-C) and RX1R II (Full frame) use totally different sensor sizes.

The SD15 was brought out 6 years before the RX1R II and that is quite a significant gap as far as technology is concerned. Each of these cameras come with different body type with the Sigma SD15 being a Mid-size SLR camera and the Sony RX1R II being a Large Sensor Compact camera.

Before we go straight into a detailed comparison, below is a quick introduction of how the SD15 matches up vs the RX1R II in terms of portability, imaging, features and an overall rating.

Normally, its tough to visualise the contrast between sensor sizing purely by reading technical specs. The photograph here may provide you a more clear sense of the sensor sizes in the SD15 and RX1R II.

As you can tell, both of these cameras posses different megapixels and different sensor sizing. The SD15 due to its tinier sensor will make shooting shallow depth of field tougher and the Sony RX1R II will deliver greater detail having its extra 37 Megapixels. Greater resolution can also help you crop pics somewhat more aggressively. The older SD15 is going to be disadvantaged in sensor innovation.
