Pentax P80 vs Sony A100 Sensor Comparison

Often, it's difficult to imagine the contrast in sensor dimensions purely by checking out specs. The picture below might provide you a much better sense of the sensor sizing in the P80 and A100.

As you can plainly see, the two cameras come with different megapixels and different sensor dimensions. The P80 having a smaller sensor is going to make shooting shallow depth of field more challenging and the Pentax P80 will produce extra detail with its extra 2 Megapixels. Higher resolution can also enable you to crop shots a good deal more aggressively. The younger P80 should have an advantage in sensor technology.
