Pentax X90 vs Ricoh GR Digital III Sensor Comparison

Typically, it can be difficult to see the contrast in sensor sizes purely by researching a spec sheet. The image here might offer you a far better sense of the sensor sizing in the X90 and GR Digital III.

Clearly, both of the cameras have different megapixel count and different sensor sizes. The X90 having a smaller sensor will make shooting shallow DOF tougher and the Pentax X90 will render extra detail using its extra 2 Megapixels. Greater resolution will also allow you to crop images a bit more aggressively. The more recent X90 is going to have an edge in sensor innovation.
