Sony A100 vs Sony W310 Sensor Comparison

Oftentimes, its tough to picture the difference in sensor dimensions just by going through specifications. The image below will help provide you a far better sense of the sensor measurements in the A100 and W310.

Plainly, both of those cameras enjoy different megapixels and different sensor dimensions. The A100 having a bigger sensor is going to make shooting shallow DOF simpler and the Sony W310 will show greater detail with its extra 2MP. Higher resolution will let you crop pictures far more aggressively. The more aged A100 will be disadvantaged in sensor innovation.
