Nikon D100 vs Sigma SD1 Sensor Comparison

Sometimes, it is very difficult to visualise the difference in sensor sizes purely by seeing a spec sheet. The picture here will provide you a stronger sense of the sensor sizes in the D100 and SD1.

As you can see, both of these cameras feature the identical sensor size but not the same megapixels. You should expect to see the Sigma SD1 to produce greater detail utilizing its extra 9 Megapixels. Greater resolution will let you crop images way more aggressively. The more aged D100 will be disadvantaged in sensor innovation.
