Olympus E-300 vs Sony A100 Sensor Comparison

In many cases, its difficult to visualise the gap in sensor dimensions simply by viewing a spec sheet. The image here may offer you a far better sense of the sensor dimensions in the E-300 and A100.

Clearly, both of the cameras provide different resolutions and different sensor dimensions. The E-300 because of its smaller sensor will make shooting shallower DOF more challenging and the Sony A100 will provide you with greater detail having its extra 2MP. Greater resolution will enable you to crop pics more aggressively. The more aged E-300 will be disadvantaged when it comes to sensor innovation.
