Pentax X90 vs YI M1 Sensor Comparison

Usually, it's difficult to visualise the contrast in sensor measurements just by checking out technical specs. The photograph underneath should give you a stronger sense of the sensor measurements in the X90 and M1.

As you have seen, the two cameras have got different megapixels and different sensor measurements. The X90 having a smaller sensor will make getting shallow depth of field trickier and the YI M1 will provide extra detail because of its extra 8 Megapixels. Higher resolution can also enable you to crop photographs much more aggressively. The older X90 will be disadvantaged in sensor technology.
