Ricoh PX vs Sigma DP1x Sensor Comparison

More often than not, it is very difficult to visualise the contrast between sensor measurements just by going over specifications. The graphic here might provide you a greater sense of the sensor sizes in the PX and DP1x.

Plainly, each of the cameras posses different megapixel count and different sensor measurements. The PX because of its tinier sensor will make getting bokeh tougher and the Ricoh PX will offer you more detail as a result of its extra 11MP. Higher resolution can also help you crop photographs somewhat more aggressively. The more modern PX is going to have an edge in sensor technology.
