Sigma SD14 vs Sony NEX-3 Sensor Comparison

Quite often, it's hard to visualise the gap between sensor sizing only by reading a spec sheet. The graphic underneath should give you a better sense of the sensor dimensions in the SD14 and NEX-3.

Clearly, both of those cameras provide the same sensor dimensions albeit not the same megapixels. You should count on the Sony NEX-3 to offer more detail with its extra 9 Megapixels. Higher resolution will also help you crop pictures more aggressively. The older SD14 is going to be disadvantaged in sensor technology.
