Sometimes, it is very hard to visualise the gap between sensor sizing merely by reviewing specifications. The photograph underneath will help provide you a stronger sense of the sensor dimensions in the SD9 and A37.

Plainly, both the cameras enjoy the same exact sensor sizing albeit not the same resolution. You should expect the Sony A37 to deliver greater detail having its extra 13 Megapixels. Higher resolution will also make it easier to crop shots far more aggressively. The older SD9 is going to be disadvantaged when it comes to sensor technology.
