Canon 40D vs Sony A900 Sensor Comparison
Normally, it's difficult to see the difference in sensor dimensions simply by going through technical specs. The picture here may offer you a much better sense of the sensor sizes in the 40D and A900.
As you can tell, each of these cameras come with different megapixels and different sensor dimensions. The 40D featuring a smaller sensor will make achieving shallower depth of field trickier and the Sony A900 will show extra detail due to its extra 15MP. Greater resolution will also let you crop images a good deal more aggressively. The more aged 40D will be disadvantaged when it comes to sensor tech.
