The PX was unveiled 3 years after the DP1 which is a fairly sizable gap as far as camera tech is concerned. Both of the cameras feature different body design with the Ricoh PX being a Compact camera and the Sigma DP1 being a Large Sensor Compact camera.

Before going right into a comprehensive comparison, here is a quick synopsis of how the PX matches up against the DP1 in the way of portability, imaging, features and an overall score.

Here is a sample of the gallery pics for Ricoh PX and Sigma DP1. The full galleries are provided at Ricoh PX Gallery and Sigma DP1 Gallery.

For those who are going to carry around your camera often, you will need to think about its weight and dimensions.

Often, it is very difficult to visualise the difference in sensor sizes simply by checking out a spec sheet. The pic below should offer you a far better sense of the sensor measurements in the PX and DP1.

As you can see, the 2 cameras come with different megapixels and different sensor sizes. The PX having a smaller sensor will make achieving shallow DOF more difficult and the Ricoh PX will produce extra detail having an extra 11MP. Greater resolution will allow you to crop photos a good deal more aggressively. The younger PX is going to have an edge when it comes to sensor tech.
