Ricoh PX vs Samsung GX-20 Sensor Comparison

Sometimes, its hard to visualise the gap between sensor sizes only by looking at specifications. The picture here might give you a greater sense of the sensor measurements in the PX and GX-20.

To sum up, the 2 cameras feature different megapixels and different sensor sizes. The PX because of its tinier sensor will make shooting shallower depth of field more challenging and the Ricoh PX will resolve greater detail as a result of its extra 1MP. Greater resolution will also make it easier to crop photos way more aggressively. The more modern PX is going to have an edge when it comes to sensor innovation.
