Pentax X90 vs Ricoh GR Sensor Comparison

Typically, it can be hard to visualise the difference in sensor dimensions purely by researching technical specs. The image below should give you a clearer sense of the sensor sizing in the X90 and GR.

As you have seen, the two cameras offer different megapixels and different sensor dimensions. The X90 using its smaller sensor will make achieving shallower depth of field harder and the Ricoh GR will render more detail with its extra 4MP. Higher resolution will help you crop pictures a little more aggressively. The more aged X90 will be disadvantaged in sensor tech.
