Ricoh PX vs Sony a1 Sensor Comparison

More often than not, it is very difficult to see the gap in sensor measurements only by checking out specifications. The visual below may give you a stronger sense of the sensor sizing in the PX and a1.

To sum up, both of these cameras offer different megapixels and different sensor measurements. The PX due to its smaller sensor will make shooting shallow depth of field tougher and the Sony a1 will provide greater detail due to its extra 34 Megapixels. Greater resolution will also make it easier to crop images a little more aggressively. The older PX will be disadvantaged in sensor technology.
