Canon A490 vs Nikon S100 Sensor Comparison

Oftentimes, it's difficult to visualise the contrast between sensor sizes merely by reviewing technical specs. The pic here should give you a more clear sense of the sensor dimensions in the A490 and S100.

As you have seen, the two cameras have got the exact same sensor measurements but not the same megapixels. You can expect to see the Nikon S100 to offer extra detail as a result of its extra 6MP. Greater resolution will also allow you to crop images much more aggressively. The more aged A490 is going to be disadvantaged with regard to sensor innovation.
