Sony W830 vs Sony A77 Sensor Comparison

In many cases, it can be tough to picture the gap between sensor sizes purely by reading through a spec sheet. The pic underneath will provide you a clearer sense of the sensor measurements in the W830 and A77.

As you can see, both of the cameras posses different resolutions and different sensor sizes. The W830 with its tinier sensor is going to make shooting shallow depth of field trickier and the Sony A77 will give extra detail using its extra 4MP. Greater resolution can also enable you to crop pics somewhat more aggressively. The more recent W830 should have an edge when it comes to sensor innovation.
