Sony W810 vs Sony A55 Sensor Comparison

Quite often, it is very difficult to visualize the gap between sensor measurements just by reading through specs. The graphic underneath may give you a far better sense of the sensor measurements in the W810 and A55.

All in all, the 2 cameras have got different megapixel count and different sensor measurements. The W810 because of its tinier sensor is going to make achieving shallow DOF more difficult and the Sony W810 will give you extra detail as a result of its extra 4 Megapixels. Greater resolution will also let you crop images much more aggressively. The newer W810 should have an edge in sensor tech.
