Epson R-D1 vs Sigma DP1 Merrill Sensor Comparison

Generally, it is difficult to envision the contrast in sensor measurements purely by going through a spec sheet. The graphic here should give you a much better sense of the sensor sizes in the R-D1 and DP1 Merrill.

Clearly, the 2 cameras posses the exact same sensor measurements but not the same megapixels. You should anticipate the Sigma DP1 Merrill to produce more detail having its extra 9 Megapixels. Greater resolution will also let you crop photos somewhat more aggressively. The older R-D1 will be behind with regard to sensor innovation.
