The Quattro was released 3 years later than the RX1 and that is quite a large difference as far as tech is concerned. Both of the cameras feature different body design with the Sigma Quattro being a Rangefinder-style mirrorless camera and the Sony RX1 being a Large Sensor Compact camera.

Before going right into a step-by-step comparison, here is a quick summary of how the Quattro grades against the RX1 in the way of portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Sigma sd Quattro & Sony Cyber-shot DSC-RX1. The complete galleries are available at Sigma Quattro Gallery & Sony RX1 Gallery.

In case you're looking to carry your camera, you are going to need to factor in its weight and proportions.

Often, it is difficult to visualise the gap between sensor sizing just by reading a spec sheet. The visual underneath should give you a stronger sense of the sensor sizes in the Quattro and RX1.

Clearly, both of these cameras come with different resolutions and different sensor sizing. The Quattro because of its tinier sensor will make shooting shallow DOF more challenging and the Sigma Quattro will offer extra detail as a result of its extra 5 Megapixels. Greater resolution will make it easier to crop photos a good deal more aggressively. The more modern Quattro will have an advantage with regard to sensor innovation.
