Ricoh GR vs Sigma DP1s Sensor Comparison

Normally, it's hard to see the contrast between sensor sizes merely by reading a spec sheet. The image here will help provide you a much better sense of the sensor measurements in the GR and DP1s.

Clearly, both of the cameras posses the exact same sensor measurements albeit not the same MP. You can count on the Ricoh GR to offer you more detail having an extra 11MP. Higher resolution will also enable you to crop pictures somewhat more aggressively. The more recent GR is going to have an edge when it comes to sensor technology.
