Pentax Q vs Sony A850 Sensor Comparison

Normally, it's tough to picture the difference in sensor dimensions purely by going through technical specs. The pic below might offer you a far better sense of the sensor measurements in the Q and A850.

As you can tell, each of the cameras provide different megapixel count and different sensor dimensions. The Q due to its smaller sensor is going to make achieving bokeh tougher and the Sony A850 will provide more detail as a result of its extra 13 Megapixels. Higher resolution can also enable you to crop pictures more aggressively. The more modern Q should have an advantage with regard to sensor innovation.
